Hi,
I'm trying to run GroupAna in matlab, but the program terminated at the very end giving the following error:
??? Undefined command/function 'grp2idx'.
Error in ==> PreProc at 66
[gij,gnj] = grp2idx(gj); % Create index vector from a grouping variable: gij is a vector
Error in ==> GroupAna at 1631
[err, Qd, s, termname, nterms, sindices, dfbothSS, modw, modwo, tnames, dfterm, dfe, Contr] = PreProc(ntot, NF, group, varnames, FL, Contr, cov, unbalanced);
Any suggestions? I can send additional information if needed.
thanks,
Chuck
