RE: st: controlling for covariates in the panel data

[Cameron McIntosh <cnm100@hotmail.com>]

I'm soon going to get a reputation as a grouch but... statistical discussion lists such as Statalist, SEMNET, etc. are not a substitute for the methodological literature. If you are new to both panel data methods and Stata then you will definitely need to do some homework, and possibly more intensive consultation and coaching. People on this list are probably willing to help you with the code, but likely only when your programming/modeling application is at a more advanced and informed stage. See:

Wooldridge, J.M. (2002). Econometric Analysis of Cross Section and Panel Data. MIT Press. 

and also the various resources at this link:

http://www.mendeley.com/research/panel-data-methods-microeconometrics-using-stata/

It also sounds like you will need a count regression model (i.e., Poisson, ZIP, etc.), and you should search for papers on "missing data and time-varying covariates"

Hope this helps,

Cam

> I have been working on tHe panel data in Stata. My regression model has some covariates which means we need to control for some variables while running the regression. To be more specific, it means that I am running the regression for the drowning rate for various counties. And wants to test whether drowning rate changes with change in various urbanization factors, controlling for doctors given in each county and the swimming pools available in each county. How do we account for covariates in the panel data? Is it just simply putting them in our regression equation or there is some other way?
