I'm interested in evaluating whether or not a survival difference exists between three release groups (~12,000 fish in each) and am in the process of evaluating the fit of my most global model (i.e., Phi(group*T), p(group*T)) prior to proceeding with formal model selection and inference. I have a very basic question regarding goodness-of-fit testing in this process....
What is the best way to proceed when component Test 2 and Test 3 Program RELEASE GOF tests have insufficient data (as indicated in output) and are nonsignificant (P>0.25 for all; also, overall tests and sums of Test 2 + Test 3 are nonsignificant)?
Thanks!
