Dear potential saviors
Recently I've had some inconsistencies in JMP depending on how I exactly tackle the problem. When I manually code the interaction of a numerical variable and a dummy variable (i.e. I multiply them), I do not get the same solution as when I just specify in the fit model box that I want to cross these effects. Moreover, when I did the same in R, I do not seem the same behavior and the two results are identical, thus leading me to suspect that it was not the manual coding of the variable that went wrong but rather that it is a peculiarity related to JMP ( I'm using a package that uses the lme4 package or the robust variant thereof, none of them show this weird behavior.).
Thanks in advance for your help and answers
