Des, Please provide some information (like the results of sessionInfo) and example code for your model. Did you use gee to fit the model and with what function? If could be that you need to examine the type argument of the predict function to make sure that you are getting the scale that you are interested in.

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.
