Dear Mike,
I'm afraid I have to ask you for help again.
I receive a following new error warning every time I try to run an FEM regardless of the constellation of variables from my dataset:
> summary(fixed1)
Error in if (pchisq(chi.squared, df = df, ncp = 0) >= upper) { :
missing value where TRUE/FALSE needed
Even if I try to run it only with first three variables (there are 146 full matrices without any missings) I have the same problem.
I appreciate any idea you can provide.
Regards,
Nastja
