I feel like I must be overlooking something obvious, but I'm doing a regression and I have a variable (group) with 3 levels. In the model coefficients, it shows a comparison of group 2-1 and group 3-1, but not group 3-2. Can you tell me why I don't need that comparison or, if I do, how to get it? Thanks very much.
PS-Jamovi is great. It would be a pain to try to use SPSS remotely.
