Sorry, I meant 0+

Would it make sense to put a floor (to 0) on observed Ys and then build a model on log(Y) as you suggested?

Thanks for you answer. It's option 2., I need to build a model that predicts only positive values, but my Ys observed are both positive and negative. I will absolutely read the article you suggest. In the meanwhile, thanks again.

Hello everybody, is it possible to add boundaries in proc quantreg? Here's my code: proc quantreg data=d algorithm=simplex outest=out ci=sparsity plots=none; model y= x1 x2 x3 / quantile=&q.; output out=out p=q res=r; run; I would like to add the following condiiton on y: y>=0 Thanks a lot.

Hello SAS experts, I'm trying to move a script from Matlab to SAS IML. I did it and it works apparently, but I am getting different results with the functions: Matlab x = lsqcurvefit(f, p, GC, DD'); SAS: /* fun=f-dd and GC already set as parameter in fun.*/ CALL NLPLM (rc, xr, "fun", p, opt); Are they equivalent? According to the documentation it seems so. Thanks a lot.

Is SAS IML NLPLM function equivalent to MATlab lsqcurvefit function?
