If you want to create stabilized weights, you can run a tab to get the proportion in each category, and then calculate your weights. WebbThis approach assumes that the correlation arises among repeated measures as the regression coefficients vary across individuals. That is, each subject is assumed to have an (unobserved) underlying level of response which persists across thepmeasurements. This subject effect is treated as random and the model becomes
