Hi Steve,
thanks a lot for your help. As for the contrast, do I get a cope of the
AGEXTASK interaction by giving a 1 weighting to both the task comparison and
the age EV (e.g.,C_interaction: 1 1 0 0 0 0 0 0)? Or does a contrast with
only a 1 for task now give the interaction (1 0 0 0 0 0 0 0) ?
thanks,
Tessa
