Hi everybody, I have a question concerning occasion covariate. Must I check the ‘sort input’ box in the run options pane? In my case I have four visits thus four occasions. How do you interpret the results? (eta tab…) Thanks a lot. Phil
Hi Phillip, if I’ve understood your question properly I hope the following helps; If at each occasion the time clock is reset to 0 and you assume full washout of the drug, you need to uncheck the sort option. Then you need in your data set a reset column or evid like in nonmem where you put for example 4 at the beginning of each occasion. Then you go to input options and click on reset. You write then as lower and upper value 4 and you are done. Of course I assume you define the inter occasion parameter and covariate. If you need more help, an example project would really help. Simon.
