Wrapper around modeling function to make them behave enough alike that Wald tests and Likelihood ratio are easy to do.
To implement a new type of zero-inflated model, extend this class.
Depending on how different the method is, you will definitely need to override the fit
method, and possibly the model.matrix
, model.matrix<-
, update
, coef
, vcov
, and logLik
methods.
