*“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) -------------------------------------------- Maximum Likelihood estimation Newton-Raphson maximisation, 150 iterations Return code 4: Iteration limit exceeded.
