Re: Panel Estimation

that means one can choose a particular one depending on his/her own choice...that is; one that best fits the model (sine Adj R2 is sensitive to these alternatives)

Re: Panel Estimation

Although this is not related to my original question still I want kw: when should i choose "simultaneous updating", "sequential updating" , "iterate coef to converge" or "update coefs once".....please give a reply.

Re: Panel Estimation

when i choose "simultaneous updating" Convergence is achieved after different weight iteration for different lags....next what?

Re: Panel Estimation

yes there is an option and by default eviews 7 set this iterate coefficients to converge (under "update weights once, then..."). However, there are other options "Iterate weights and coefficients" but I dont know when to choose this option. I hv read the Eviews mannual but I dont...

Panel Estimation

I am estimating a fixed effect model in Eviews 7. When i estimate the model without correcting heterscadasticity I get the result with AIC. But the moment I choose GLS weights : Cross-section Sur and coef covarience method: white cross-section, I dont get AIC/SIC value in the dispaly. Why does this ...

Choice between standard errors

Hi guys, m estimating a panel model. Here I need to correct for heteroscadisity. But m bit confused about different corrective tools. In particular I want to know what criterion should one follow to choose between White cross-section standard errors and White diagonal standard errors approaches. Ple...

Re: Role of R-squared

yes you are correct....but notice that after correction your t-value of coefficients is very low while R-square is quite large, so there is an evidence of multicollinearity. Do a multicollinearity test of your origunal variables before you interpret your findings.

Re: Regarding Assumptions

my problem is not estimating the model in eviews.....rather i am looking for justification of using MLE in "spatial lag model"!!!! How does MLE provide efficient estimator in case of spatial lag model.??
