[Gretl-users] About GJR-garchm and gig

Dear all I wrote a gretl package named GJR-garchm (GJR GARCH in mean). It works ok since gretl 1.8.6. However, with gretl 1.9.1, after executing "GJR-garchm" download from the server, I got two warnings: Warning: pow: Numerical result out of range Warning: pow: Numerical result out of range Is there anything wrong? Or what does the message mean? By the way, as I can recall, gig (garch in gretl, a packages for estimating models of GARCH family) works great since ver. 1.8.6. But it is no working anymore in gretl 1.9.1. Does anyone have a clue? Yi-Nung
