Expand family in qgam #36

Closed Alectoria closed 4 years ago

This is a request for an enhancement: It would be great if qgam would have the same range of families as family.mgcv in gam, e.g. the beta regression family to fit true % data.

Dear Victoria, note that qgam estimates quantile regression models, that is models where there is no parametric assumption on the distribution of the dependent variable, y. Hence, if you think that the response y follows a beta, gamma, Gaussian or any other distribution you should fit a GAM model gam() using mgcv, not a quantile GAM. With qgam you can model the distribution of y without making any such assumption, that is without specifying any family. That is why the qgam function does not have an argument called family. But maybe I am misunderstanding your request?
