Follow-up MANCOVA interaction?

jamie canataro
I have a question regarding a MANCOVA interaction and was wondering for some assistance.

  I am performing a 2 X 3 MANCOVA and have received significant results on an interaction.  I am looking to follow-up the significant interaction to determine which of the specific means are statistically different.  Would this require me to create a syntax program? And if so, how can I acquire/create/borrow the syntax.

  Thank you in advance.

Jamie...at this juncture I'm assuming the interaction is with the fixed factors (as opposed to the IV x covariate interaction which tests the homogeneity of regression assumption).......with a significant interaction, you may want to consider a simple effects analysis, and you would need to use the syntax (e.g., in syntax reference guide on GLM) as follows:

  /emmeans = tables (A *B) compare (A) adj (method)

  method can be Sidak or Bonferroni or LSD................
