Re: [Gretl-users] panel regression result interpretation

Hi Neha,              I think the choice of whether to integrate a dummy variable or not depends on the objective of your research. What are you searching for?. Have your companies been randomly selected(then a GLS with  random effect is feasible) or constituted firms within a confined region: which you all choose(then a GLS with Fixed effect is feasible). From results of the Hausman  test, estimates by OLS are efficient but not consistent: indicating the absence of endogeneity and vailidity of a GLS with Random effect. I can't really be of help untill I understand the essence of integrating a dummy variable in your research objective. ________________________________ From: Neha Kalra <nehakalra56(a)yahoo.co.in&gt; To: gretl-users(a)lists.wfu.edu Sent: Sunday, October 30, 2011 4:01 PM Subject: [Gretl-users] panel regression result interpretation Hello to all Gretl users, i need help regarding to panel regression that i m running on the data of 49 companies over 5 years.. disclosure score have been assigned to each company is my dependent variable and i m seeing relation of this with diffrent variable like assets, debt to eqity ratio, working capital etc.... I have run a random effect model without dummies... following is the result of regression.. : Random-effects (GLS), using 245 observations Included 49 cross-sectional units Time-series length = 5 Dependent variable: Disclosurescore     Coefficient Std.

I m also attaching with ths mail my data file in gretl.. Plz anyone help ..
