Hello, I am trying to cacluate a effect size, but apparently I couldn't get it run. I think it's the labeling that I used caused the problem. Could you help out please? Thank you very much! MODEL: ZST37Q01 ON ZPVEPS(b1) ZPVISI(b2) ZPVUSE(b3); ZPVEPS(var1); ZPVISI(var2); ZPVUSE(var3); ZST37Q01(Theta); MODEL CONSTRAINT: new(ES1); ES = b1*(2*sqrt(var1)/sqrt(var1*b1**2+Theta));

Sorry, it's a labeling and typing mistake indeed. I have corrected it to be ES1 = b1*(sqrt(var1)/sqrt(var1*b1**2+Theta) But the estimate for ES1 is 0.476, whereas the STDYX standardization output is 0.529, and their t values are 17.190 and 13.814. Could you advice me why is this please? Thanks! 


I think your problem is that theta is a residual variance not a variance.

Oh i see. thank you. i forgot to add explained variances of the other two variables. i will take another try.
