Now open Stata, type help xt , and start exploring. The patterns hidden in your panel data are waiting to be discovered. This article originally appeared as a contributed guide for researchers using Stata for panel data analysis. For updates and advanced topics like spatial panel models or panel VAR, stay tuned for Part 2.
xtreg wage experience union i.year, fe Or using the areg command:
bysort id (year): keep if _n == 1 Merging two panel datasets requires both dimensions:
Here, country_id is the panel variable, and year is the time variable. The single most important step in Stata panel data analysis is declaring your data structure using xtset . This command tells Stata which variable identifies the panels and which identifies the time dimension. Basic Syntax xtset panelvar timevar For our example:
xtserial wage experience union Random effects assumes the unobserved panel effects are uncorrelated with your regressors. This is a strong assumption but allows inclusion of time-invariant variables.
