RegisterSignificant period effect [Design Issues]
Hi all,
Question. What can cause a period effect? Aside from carryover due to poor washout selection, and other unexplanable events (which I can't think of)?
If someone decides to analyze study samples by period instead of analyzing the samples after completion of all study periods, could that cause a significant period effect?
Is it possible to determine the interaction between period and sequence effect?
Thanks
John
