Multiple comparisons error

HotellingWombat — Thu, 08 Jun 2023 16:43:42 GMT

Hello,

I was wondering if someone who has encountered the same error could help me. I ran a repeated measures ANOVA with unstructured correlation structure and now I want to test for multiple comparisons for those interactions that gave a significant value. However, I am unable to do so because an error message keeps popping up. I'm unsure if I'm doing the analyses wrong. Please help!

Hi @HotellingWombat (great name!),

I have not seen this error before. It is difficult to understand what might be causing this without knowing more about the data and analysis that you need to do. This might be better handled by JMP Technical Support (email: support@jmp.com).

I hope that helps,

Phil

Hello, and welcome! It's impossible to say without knowing more about the data structure. That said...there may be no degrees of freedom left over for error. i.e., you are trying to estimate n-1 effects with n points. Can you provide more detail and context about your data and what you hope to get out of it?
