do you mean that every single case in your dataset is in the same condition? if that is the case, you cannot use variable A as a predictor, as there is no variability you cannot say anything about it's effects.I have variable A (with a condition same for all cases),
what do you mean by "are present"?a moderator variable B and the outcome variable C. I'm trying to see if variable A condition and variable C conditions are present, to what extent variable B mediates variable C?
this is unclear.I've tried to write a simple syntax to compute two variables: New_Variable_1 (variable A if Moderator Variable B >0, & Variable 3) and New_Variable_2 (variable A if Moderator Variable B =0 & variable 3). So then I could compare them to variable 3.
