Two groups (e.g. logistics) [Design Issues]
Dear Sangeea,
since I recently had to deal with deficiency letters from the Gulf States (Saudia Arabia, Emirates), I would suggest the following procedure:
If the ‘Treatment × Group Interaction’ term is statistically not significant (p>0.05), the simple model (i.e., naïve pooling of data without both Group-terms) can be applied.*
since I recently had to deal with deficiency letters from the Gulf States (Saudia Arabia, Emirates), I would suggest the following procedure:
Fixed: Sequence + Treatment + Period + Group + Treatment × Group
Random: Subject(Sequence)
If the ‘Treatment × Group Interaction’ term is statistically not significant (p>0.05), the simple model (i.e., naïve pooling of data without both Group-terms) can be applied.*
