Unbalanced Panel data - regression

Hi,

I am new to using eviews and regressions so I really need a little urgent help.

I have a dataset of n = 212 companies and t = 10 years and a total of 1561 observations. I have an unbalanced panel. I'm testing 5 independent variables.

As far as I understand I am supposed to use a "Fixed effects model" for the regression.

I know it is alot to ask but does anyone have any tips on how to move forward and on what steps need to be taken in order to perform such a regression using eviews?

Thanks in advance for your help.

Rauf

I'm not an expert myself, but have done something similar. You will first need to assess whether your data is distributed normally, you can find this out through the jarque-bera test. If it is 0.01 or lower you'll need to execute non-parametric test, if not you can execute parametric tests like the pearson's correlation or t-test..

Hope this helps you a little. Try posting and bothering everybody around you, you'll get there.

I'm afraid this is bad advice. Whether the data is distributed normally is completely irrelevant. The error terms being distributed normally matters a little, but even that isn't very important in large datasets unless the deviation from normality is very large.

Sorry, it's true that the residual distribution needs to be checked instead of the distribution of the data.

-Starz, could you tell me which buttons to press/commands to give in order to execute a spearman rank test? I want to be able to reflect on the difference between the outcome of a OLS and a spearman rank.. Thanks

Make a group, choose View/Covariance analysis and flip Method to Spearman rank-order. That may have what you want.
