Also, xtsur (as per the stata help) perform a one way random effect estimation of SUR in a panel data set. Therefore when I want to estimate the system in a panel data using industry and year fixed effects ( data has fixed rather than random effects, tested before) , I use the following command:This talk: overview of panel data methods and xt commands for Stata 10 most commonly used by microeconometricians. Three specializations to general panel methods: 1 Short panel: data on many individual units and few time periods. Then data viewed as clustered on the individual unit. Many panel methods also apply to clustered data such as Panel Data Panel data is obtained by observing the same person, firm, county, etc over several periods. Unlike the pooled cross sections, the observations for the same cross section unit (panel, entity, cluster) in general are dependent. Thus cluster-robust statistics that account for correlation within panel should be used.Autocorrelation. Iterated GLS with autocorrelation does not produce the maximum likehood estimates, so we cannot use the likelihood-ratio test procedure, as with heteroskedasticity. However, Wooldridge (2002, 282–283) derives a simple test for autocorrelation in panel-data models. Drukker (2003) provides simulation results showing that the ...ORDER STATA Panel-data unit-root tests . Stata implements a variety of tests for unit roots or stationarity in panel datasets with xtunitroot.The Levin–Lin–Chu (2002), Harris–Tzavalis (1999), Breitung (2000; Breitung and Das 2005), Im–Pesaran–Shin (2003), and Fisher-type (Choi 2001) tests have as the null hypothesis that all the panels contain a unit root.Panel-data analysis using Stata.
