Panel data stata.

I am using Stata 13 to analyze a large panel. After setting the panel structure In oder to get a feel for the data I used xtsum to get some intial descriptives. I have two groups, which I compare so I ran xtsum for the entire data set, and for each group indivdiually. I realized that there are a few variables that have very high averages and ...I'm running a panel data regression, with 5 independent variables and 28 firms over 5 years. I have 140 observations. After running a Hausman test, i found that a FE reg is to be used. Next I tested for heteroscedasticity - using the Cook-Weisberg httest for residuals - and autocorrelation - using the xtserial command for panel data.3. A convenient alternative is provided by the "unique" package. Here's a quick example: * Install the unique package ssc inst unique * Load toy dataset sysuse auto, clear * Get a quick report of unique (and total) values for a variable unique mpg * The result will be available as r (unique) return list. Share.I am trying to calculate fitted values from xtpoisson fixed effects on out-of-sample data. I know how to calculate fitted values for in-sample predictions (using the stata auto data), and the below code is what I use to transform the output from the post-estimation command "predict, xb".

29 Oct 2016, 18:44. Yes, it works the same way in panel data. The log is the log. Of course, if your variable takes on zero or negative values then you can't do this (whether panel data or not). And whenever I see someone starting to log transform data, I always wonder why they are doing it. Sometimes there are good reasons, but there tends to ...Dear Stata community, currently, I am trying to decide whether my data is normally distributed or not using the Jarque-Bera test.
