*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)
