*?In the name of God?*
*Hi dear*
I try to analyze a regression model but can?t. I have 2 problem in this
presses as below:
And also I send you details in attached file.
Best Regards
One of the is:
> phtest(fixed,random)
Error in solve.default(dvcov) :
system is computationally singular: reciprocal condition number 1.34013e-25
and another one is :

fixedglm=pglm(RiskTaking~HHI+GDPGROWTH+EBIT+MB+DEBT+bonus+FATA+MKTSIZE+factor
+
(indu),data=data1,index=c("code","year"),model="within",family="gaussian")
> summary(fixedglm)
