Jacobian inclusion of extra theta parameters #9

Open eenticott opened 1 year ago

eenticott commented 1 year ago

When calculating the Jacobian for the family, the lpi does not include any information about the thetas, so they are missed. This causes a mismatch of dimensions between Dfx and the output of varFun.

Also need to look at the model matrix, the theta columns are set to 0 when fitting the model, but we might need them to be 1 to properly calculate the jacobian.

When looking at the linear predictor, anything related to the theta should be dropped. In particular, the columns of 0 can be dropped from the model, as the theta has no relationship with the linear predictor.
