+# resultsFactory
+
+> Create a new constructor for creating a two-sample Z-test results object.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var resultsFactory = require( '@stdlib/stats/base/ztest/two-sample/results/factory' );
+```
+
+#### resultsFactory( dtype )
+
+Returns a new constructor for creating a two-sample Z-test results object.
+
+```javascript
+var Results = resultsFactory( 'float64' );
+// returns
+
+var r = new Results();
+// returns
+```
+
+The function supports the following parameters:
+
+- **dtype**: floating-point data type for storing floating-point results. Must be either `'float64'` or `'float32'`.
+
+
+
+
+
+
+
+
+
+## Notes
+
+- A results object is a [`struct`][@stdlib/dstructs/struct] providing a fixed-width composite data structure for storing two-sample Z-test results and providing an ABI-stable data layout for JavaScript-C interoperation.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Float32Array = require( '@stdlib/array/float32' );
+var resultsFactory = require( '@stdlib/stats/base/ztest/two-sample/results/factory' );
+
+var Results = resultsFactory( 'float64' );
+var results = new Results({
+ 'rejected': true,
+ 'alpha': 0.05,
+ 'pValue': 0.3364,
+ 'statistic': 11.7586,
+ 'nullValue': 0.0,
+ 'sd': 0.4563,
+ 'ci': new Float64Array( [ 9.9983, 11.4123 ] ),
+ 'alternative': 'two-sided'
+});
+
+var str = results.toString({
+ 'format': 'linear'
+});
+console.log( str );
+
+Results = resultsFactory( 'float32' );
+results = new Results({
+ 'rejected': true,
+ 'alpha': 0.05,
+ 'pValue': 0.3364,
+ 'statistic': 11.7586,
+ 'nullValue': 0.0,
+ 'sd': 0.4563,
+ 'ci': new Float32Array( [ 9.9983, 11.4123 ] ),
+ 'alternative': 'two-sided'
+});
+
+str = results.toString({
+ 'format': 'linear'
+});
+console.log( str );

+# Float32Results
+
+> Create a two-sample Z-test single-precision floating-point results object.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var Float32Results = require( '@stdlib/stats/base/ztest/two-sample/results/float32' );
+```
+
+#### Float32Results( \[arg\[, byteOffset\[, byteLength]]] )
+
+Returns a two-sample Z-test single-precision floating-point results object.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+```
+
+The function supports the following parameters:
+
+- **arg**: an [`ArrayBuffer`][@stdlib/array/buffer] or a data object (_optional_).
+- **byteOffset**: byte offset (_optional_).
+- **byteLength**: maximum byte length (_optional_).
+
+A data object argument is an object having one or more of the following properties:
+
+- **rejected**: boolean indicating whether the null hypothesis was rejected.
+- **alternative**: the alternative hypothesis (e.g., `'two-sided'`, `'less'`, or `'greater'`).
+- **alpha**: significance level.
+- **pValue**: p-value.
+- **statistic**: test statistic.
+- **ci**: confidence interval as a [`Float32Array`][@stdlib/array/float32].
+- **nullValue**: mean under the null hypothesis.
+- **sd**: standard error of the mean.
+
+#### Float32Results.prototype.rejected
+
+Boolean indicating whether the null hypothesis was rejected.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.rejected;
+// returns
+```
+
+#### Float32Results.prototype.alternative
+
+The alternative hypothesis.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.alternative;
+// returns
+```
+
+#### Float32Results.prototype.alpha
+
+Significance level.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.alpha;
+// returns
+```
+
+#### Float32Results.prototype.pValue
+
+The test p-value.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.pValue;
+// returns
+```
+
+#### Float32Results.prototype.statistic
+
+The test statistic.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.statistic;
+// returns
+```
+
+#### Float32Results.prototype.ci
+
+Confidence interval.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.ci;
+// returns
+```
+
+#### Float32Results.prototype.nullValue
+
+Mean under the null hypothesis.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.nullValue;
+// returns
+```
+
+#### Float32Results.prototype.sd
+
+Standard error of the mean.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.sd;
+// returns
+```
+
+#### Float32Results.prototype.toString( \[options] )
+
+Serializes a results object to a formatted string.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.toString();
+// returns
+```
+
+The method supports the following options:
+
+- **digits**: number of digits to display after decimal points. Default: `4`.
+- **decision**: boolean indicating whether to show the test decision. Default: `true`.
+
+Example output:
+
+```text
+
+Two-sample Z-test
+
+Alternative hypothesis: True mean is less than 1.0
+
+ pValue: 0.0406
+ statistic: 9.9901
+ 95% confidence interval: [9.7821, 10.4451]
+
+Test Decision: Reject null in favor of alternative at 5% significance level
+
+```
+
+#### Float32Results.prototype.toJSON( \[options] )
+
+Serializes a results object as a JSON object.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.toJSON();
+// returns {...}
+```
+
+`JSON.stringify()` implicitly calls this method when stringifying a results instance.
+
+#### Float32Results.prototype.toDataView()
+
+Returns a [`DataView`][@stdlib/array/dataview] of a results object.
+
+```javascript
+var results = new Float32Results();
+// returns {...}
+
+// ...
+
+var v = results.toDataView();
+// returns
+```
+
+
+
+
+
+
+
+
+
+## Notes
+
+- A results object is a [`struct`][@stdlib/dstructs/struct] providing a fixed-width composite data structure for storing two-sample Z-test results and providing an ABI-stable data layout for JavaScript-C interoperation.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var Results = require( '@stdlib/stats/base/ztest/two-sample/results/float32' );
+
+var results = new Results({
+ 'rejected': true,
+ 'alpha': 0.05,
+ 'pValue': 0.3364,
+ 'statistic': 11.7586,
+ 'nullValue': 0.0,
+ 'sd': 0.4563,
+ 'ci': new Float32Array( [ 9.9983, 11.4123 ] ),
+ 'alternative': 'two-sided'
+});
+
+var str = results.toString({
+ 'format': 'linear'
+});
+console.log( str );
+```
+
+
+
+
+
+
+
+* * *
+
+
+
+## C APIs
+

+# Float64Results
+
+> Create a two-sample Z-test double-precision floating-point results object.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var Float64Results = require( '@stdlib/stats/base/ztest/two-sample/results/float64' );
+```
+
+#### Float64Results( \[arg\[, byteOffset\[, byteLength]]] )
+
+Returns a two-sample Z-test double-precision floating-point results object.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+```
+
+The function supports the following parameters:
+
+- **arg**: an [`ArrayBuffer`][@stdlib/array/buffer] or a data object (_optional_).
+- **byteOffset**: byte offset (_optional_).
+- **byteLength**: maximum byte length (_optional_).
+
+A data object argument is an object having one or more of the following properties:
+
+- **rejected**: boolean indicating whether the null hypothesis was rejected.
+- **alternative**: the alternative hypothesis (e.g., `'two-sided'`, `'less'`, or `'greater'`).
+- **alpha**: significance level.
+- **pValue**: p-value.
+- **statistic**: test statistic.
+- **ci**: confidence interval as a [`Float64Array`][@stdlib/array/float64].
+- **nullValue**: mean under the null hypothesis.
+- **sd**: standard error of the mean.
+
+#### Float64Results.prototype.rejected
+
+Boolean indicating whether the null hypothesis was rejected.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.rejected;
+// returns
+```
+
+#### Float64Results.prototype.alternative
+
+The alternative hypothesis.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.alternative;
+// returns
+```
+
+#### Float64Results.prototype.alpha
+
+Significance level.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.alpha;
+// returns
+```
+
+#### Float64Results.prototype.pValue
+
+The test p-value.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.pValue;
+// returns
+```
+
+#### Float64Results.prototype.statistic
+
+The test statistic.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.statistic;
+// returns
+```
+
+#### Float64Results.prototype.ci
+
+Confidence interval.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.ci;
+// returns
+```
+
+#### Float64Results.prototype.nullValue
+
+Mean under the null hypothesis.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.nullValue;
+// returns
+```
+
+#### Float64Results.prototype.sd
+
+Standard error of the mean.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.sd;
+// returns
+```
+
+#### Float64Results.prototype.toString( \[options] )
+
+Serializes a results object to a formatted string.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.toString();
+// returns
+```
+
+The method supports the following options:
+
+- **digits**: number of digits to display after decimal points. Default: `4`.
+- **decision**: boolean indicating whether to show the test decision. Default: `true`.
+
+Example output:
+
+```text
+
+Two-sample Z-test
+
+Alternative hypothesis: True mean is less than 1.0
+
+ pValue: 0.0406
+ statistic: 9.9901
+ 95% confidence interval: [9.7821, 10.4451]
+
+Test Decision: Reject null in favor of alternative at 5% significance level
+
+```
+
+#### Float64Results.prototype.toJSON( \[options] )
+
+Serializes a results object as a JSON object.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.toJSON();
+// returns {...}
+```
+
+`JSON.stringify()` implicitly calls this method when stringifying a results instance.
+
+#### Float64Results.prototype.toDataView()
+
+Returns a [`DataView`][@stdlib/array/dataview] of a results object.
+
+```javascript
+var results = new Float64Results();
+// returns {...}
+
+// ...
+
+var v = results.toDataView();
+// returns
+```
+
+
+
+
+
+
+
+
+
+## Notes
+
+- A results object is a [`struct`][@stdlib/dstructs/struct] providing a fixed-width composite data structure for storing two-sample Z-test results and providing an ABI-stable data layout for JavaScript-C interoperation.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Results = require( '@stdlib/stats/base/ztest/two-sample/results/float64' );
+
+var results = new Results({
+ 'rejected': true,
+ 'alpha': 0.05,
+ 'pValue': 0.3364,
+ 'statistic': 11.7586,
+ 'nullValue': 0.0,
+ 'sd': 0.4563,
+ 'ci': new Float64Array( [ 9.9983, 11.4123 ] ),
+ 'alternative': 'two-sided'
+});
+
+var str = results.toString({
+ 'format': 'linear'
+});
+console.log( str );
+```
+
+
+
+
+
+

+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/stats/base/ztest/two-sample/results/float64.h"
+```
+
+#### stdlib_stats_ztest_two_sample_float64_results
+
+Structure for holding double-precision floating-point test results.
+
+```c
+#include
+#include
+
+struct stdlib_stats_ztest_two_sample_float64_results {
+ // Boolean indicating whether the null hypothesis was rejected:

+# structFactory
+
+> Create a new [`struct`][@stdlib/dstructs/struct] constructor tailored to a specified floating-point data type.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var structFactory = require( '@stdlib/stats/base/ztest/two-sample/results/struct-factory' );
+```
+
+#### structFactory( dtype )
+
+Returns a new [`struct`][@stdlib/dstructs/struct] constructor tailored to a specified floating-point data type.
+
+```javascript
+var Struct = structFactory( 'float64' );
+// returns
+
+var s = new Struct();
+// returns
+```
+
+The function supports the following parameters:
+
+- **dtype**: floating-point data type for storing floating-point results. Must be either `'float64'` or `'float32'`.
+
+
+
+
+
+
+
+
+
+## Notes
+
+- A [`struct`][@stdlib/dstructs/struct] provides a fixed-width composite data structure for storing two-sample Z-test results and provides an ABI-stable data layout for JavaScript-C interoperation.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var resolveEnum = require( '@stdlib/stats/base/ztest/alternative-resolve-enum' );
+var Float64Array = require( '@stdlib/array/float64' );
+var Float32Array = require( '@stdlib/array/float32' );
+var structFactory = require( '@stdlib/stats/base/ztest/two-sample/results/struct-factory' );
+
+var Struct = structFactory( 'float64' );
+var results = new Struct({
+ 'rejected': true,
+ 'alpha': 0.05,
+ 'pValue': 0.3364,
+ 'statistic': 11.7586,
+ 'nullValue': 0.0,
+ 'sd': 0.4563,
+ 'ci': new Float64Array( [ 9.9983, 11.4123 ] ),
+ 'alternative': resolveEnum( 'two-sided' )
+});
+
+var str = results.toString({
+ 'format': 'linear'
+});
+console.log( str );
+
+Struct = structFactory( 'float32' );
+results = new Struct({
+ 'rejected': true,
+ 'alpha': 0.05,
+ 'pValue': 0.3364,
+ 'statistic': 11.7586,
+ 'nullValue': 0.0,
+ 'sd': 0.4563,
+ 'ci': new Float32Array( [ 9.9983, 11.4123 ] ),
+ 'alternative': resolveEnum( 'two-sided' )
+});
+
+str = results.toString({

+
+
+## Usage
+
+```javascript
+var res2str = require( '@stdlib/stats/base/ztest/two-sample/results/to-string' );
+```
+
+#### res2str( results\[, options] )
+
+Serializes a two-sample Z-test results object as a formatted string.
+
+```javascript
+var Float64Results = require( '@stdlib/stats/base/ztest/two-sample/results/float64' );
+
+var results = new Float64Results();
+
+// ...
+
+var s = res2str( results );
+// returns
+```
+
+The function supports the following parameters:
+
+- **results**: two-sample Z-test results object.
+- **options**: function options.
+
+The function supports the following options:
+
+- **digits**: number of digits to display after decimal points. Default: `4`.
+- **decision**: boolean indicating whether to show the test decision. Default: `true`.
+
+
+
+
+
+
+
+
+
+## Notes
+
+- Example output:
+
+ ```text
+
+ Two-sample Z-test
+
+ Alternative hypothesis: True mean is less than 1.0
+
+ pValue: 0.0406
+ statistic: 9.9901
+ 95% confidence interval: [9.7821, 10.4451]
+
+ Test Decision: Reject null in favor of alternative at 5% significance level
+
+ ```
+
+
+
+
+
+
