Assumption of linearity

[juandavidgutier]

Hi developers team,

I have a question about the models IRM and IIVM do they both impose the assumption that the outcome is a linear function of the treatment, or they are fully flexible non-parametric estimators of the relationship between the treatment and the outcome? And by the name, I assume that the models PLR and PLIV impose this linear assumption.

Thanks a lot for your answer.

I lock this conversation because it is redundant to the one opened in the Python repository.

I'd encourage everyone interested to comment and discuss the question there 😄
