[Gretl-users] Vvariables orthogonalization

Hi, I tried to replicate in gretl exercise with variable orthogonalization explained in https://www.stata.com/manuals13/rorthog.pdf but after running the script (dataset in attachment): <hansl> set verbose off list X = const length weight headroom trunk  X_orth = qrdecomp({X}) series olength = X_orth[,2] series oweight = X_orth[,3] series oheadroom = X_orth[,4] series otrunk = X_orth[,5] ols price X --simple ols price const olength oweight oheadroom otrunk --simple </hansl> the only identical coefficient is for const. What am I doing wrong? Regards, Marcin -- Marcin Błażejowski
