Covariables Polort

The REST toolbox is coded as follows;
" Covariables Polort (Polynomial Orthogonal Degree): 0 "

Is it right? I think this code can't regress out covariables because '0' means not to use this function.

Please comments.

What number is right for covariables polort?

Hi!
1 means the linear trend will be also regressed out in the regression model.
0 means the linear trend will NOT be regressed out in the regression model. However, the other specified covariates will be regressed out.
