hi Namir,
in BestMLR2 there is a little typo: YMean and Ymean; to correct it I simply change the namevar in Local definition...
However is a very useful program!
All the suite of these programs should be inside the FW of Prime, perhaps with other programs to analyze multiple regression, thank you to have done them!
