Does anybody know how I can constrain the correlation between two random effect to be 1?
I know about the PARMS statement (with the hold option), but with this statement I can constrain the Co-variance, but is there a direct way to constrain the correlation itself?
I don't know whether this will work, but it is possible to specify the covariance structure as being based on the correlations, using type=unr. From there, it seems possible that you could constrain a correlation to be a fixed value.
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
