Dear Forum members,  

I have created a quasi-poisson model from a training dataset and now wish to use the model to estimate y values for a test dataset, in order to validate the model. The trouble is I can't figure out how to estimate y values for the test set using the model derived from the training set. I've been fiddling about with predict(), but can't seem to get the desired result. Could somebody help please? Thanks very much in advance.  

Best wishes,
