Hi everyone,

I've been trying to use aoctool to compare two groups with one covariate as follows:

[h,atab,ctab,outstats] = AOCTOOL(X,Y,G)

X being a vector of the data, Y being a vector of covariate, G being the grouping.

Now I would like to actually just know the p-value for a comparisons between the values in X (divided by group and using the covariate Y). Is it then just to run:

c = multcompare(outstats,0.05);

And if the last value (which should be the p-value) is significant, then the two groups (X) are significantly different when considering the variable (Y)? Or am I missing a step?

Thanks a lot,

Eric
