hi,buddys,I'd like to use proc panel to analyze whether following independent variable:
fage(forecast horizon),
bsize(brokerfirm's scale),
affil(affiliation between stock and brokerfirms,dummy variable, if they have affiliation,then affil=1,otherwise 0),
freq(forecast frequency of each broker for each stock and each year),
affect broker's ferro (forecast erro).
following is my sample:
stock rptyear ferro fage bsize affil freq brokercd
702 2009 0,0166 0.793 3,259 1 0,69 GX01
702 2007 0,0161 0,0194 2,863 0 0.39 GY02
702 2008 0.028 1,028 5,860 1 0.22 SY01
703 2009 0,35 0,353 2,748 0 0.44 SY01
703 2008 1,028 2,295 0.781 1 0.33 GX01
........
my program is :
proc sort data=a;
by brokercd rptyear;
run;
proc panel data=a;
model ferro= fage bsize affil freq;
id brokercd rptyear;
run;
the log result is :procedure panel not found!
what's wrong? who can help me,please!thanks very much!
