The possibility of running pooled mean group estimation in dynamic heterogeneous panels is a feature that I also wish that could be available in a future Eviews update.

Many thanks Glenn for the explanation. However, as I´m not an expert I'm still a litle bit confused. I found some references mentioning that the Parks-Kmenta method specifies a model for heteroskedasticity, a model for contemporaneous correlation, and also the following model for serial correlation ...

Hi, I have a doubt concerning the equivalence between the panel "Cross-section SUR" class of covariance structures and the Parks-Kmenta model. The Parks model specifies a model for heteroskedasticity, contemporaneous correlation, and serial correlation AR(1). I believe that in Eviews7 I ne...

Would it be correct to include a Lagged Dependent Variable in a Panel with Fixed Effects using LS with Cross section SUR Weights?

I have updated and the problem persists. I have compared the regression outputs of the pool with the panel and I suspect that there is a bug in the estimation of the log likelihood of the pool with cross section weights and fixed effects. Below you can find the comparison the results of the pool and...

Many thanks again.

I have no idea where the problem may lie...

The data is the same. less restrictive model results: Dependent Variable: LOG(LONG_RUN_COST?) Method: Pooled EGLS (Cross-section weights) Date: 04/01/12 Time: 18:03 Sample: 2014 2028 Included observations: 15 Cross-sections included: 11 Total pool (balanced) observations: 165 Iterate weights to conv...

I´ve checked with another pair of nested models and the problem persists. model 1 (more restricted) with log likelihood 247,5779 model 2 (less restricted) with log likelihood -234.3651 Thus apllying the likelihood ratio test: 2X(log likelihood(m2)-log likelihood(m1))= -963,886 Knowing that the likel...

Dear Glenn, Still one related issue for which I would much appreciate any help that you can provide. I got the log likelihood values of 2 models and used them to compare the models' hypothesis by means of a likelihood ratio test. The result of the ratio is negative, which is fine (-1381.81). Knowing...

Problem solved. Many thanks Glenn. I did not select the iterate box...

Dear all, I'm estimating panel data models using the pool object because it returns the covariance matrix and the correlation matrix. However, I notice that the output does not included log likelihood when the estimation is done using cross section sur weights (only with pooled least squares). Is th...

Dear Gareth,

Would it be possible to post the answer/google link again (the link is not working).

Many thanks

Hi, I have produced some dated tables from group objects. I want to have thousand separators in the cells but the although the option is selected (Options/general options/spreadsheets/thousand separator - checkbox selected) the thousand separators are not made. As I'm processing many tables this is ...

I have the same doubt...

By the way, if I want to specify a unrestricted model where the intercept and slope coefficients are allowed to vary across cross sections (individuals) then I will have: dependent variable, 11 dummies, 22 independent variables (11 dummies * independent variable 1 + 11 dummies multiplied by independ...
