Greetings Statalisters.
I am working on a multiple comparison problem comparing Y by Group with 4 groups, but I have MULTIPLE Y's that I need to consider because my Y's represent fold-increases in gene expression data and I'm working with over 40 genes...
So in this effort, I'd like to run Oneway ANOVAs of Y by Group for each of my genes, capture the Pairwise comparisons among my groups into a separate dataset, and repeat this with a loop for each of the genes of interest.
Ideally I'd like to use the Tukey-Kramer Pairwise user-written command (thanks Phil Enders), however that does not provide p-values in the screen output or any matrix in the return list.
An alternative would be to use the Scheffe posthoc option to -oneway- but I can't figure out how to steal those p-values either?
Any thoughts on how to grab these p-values?
Much appreciated...
Rob
