Thank you prof.Brian ripley for you suggestion.
Once I get the parameters from nnls.fit, I'd like to have also the
significance of the estimators, but the vcov() command (which I tried to
obtain the var-covar of the estimators,because nnls.fit doesn't give it)
doesn't give any results.
Did anyone have a suggestion on how to calculate the standard error of such
estimators?
Thank you
