MANOVA, Repeated Measure: How to test difference between pairs of groups out of multiple groups

Hi JMP Community,

 

I'm interested in analyzing the attached data using Repeated Measures MANOVA:

  • Data represents repeated measurements within subjects
  • 5 time points: W2 - W12
  • 3 Groups: Control, Group A, and Group B

Is it possible to test the difference between pairs of groups across the time course:

  • Control vs. Group A
  • Control vs. Group B
  • Group A vs. Group B

Also, when selecting the Test Each Column Separately option, the tests return non-significant p values even though the Control group appears to be clearly different from the Group A and B. What am I missing?

By the way, I did read the help material provided but I did not find answers to these questions.

 

Thank you for your help.

 

Sincerely,

 

TS
