Re: Problem with prediction



Dear Nick,

I attach the .pvs file from which I note that the
predicted splines start at line 26 of the file.

So the Splus command needs to be 
asr.pvsplot("c:\\docs\\dracup_m\\96wh14\\test.pvs",26,5,12)


                                                   ^^
                                                   
Arthur
