Using nlswork.dta (N=28,534 observations, 4,710 individuals):
Once the data is set as panel, you can use a series of xt commands. to analyze it. A useful visualization command is xtline, type: Princeton University Stata Longitudinal-Data/Panel-Data Reference Manual
This article is your definitive guide to analysis. Whether you are a graduate student wrestling with your first panel dataset or a researcher refining a complex model, this guide will walk through preparation, exploration, modeling, diagnostics, and advanced techniques. stata panel data

To ensure reproducible, reliable, and publication‑ready results, adopt these habits: Using nlswork
Before any xt command can be run, you must first define the panel's structure using the xtset command. This informs Stata which variable uniquely identifies the cross-sectional unit and which variable denotes time. The basic syntax is xtset panelvar timevar , where panelvar is the individual identifier and timevar is the time index.
To view the trajectories of your variables over time for individual units, use xtline : xtline GDP if country_id <= 5 Use code with caution. Whether you are a graduate student wrestling with
Stata makes it easy to mathematically determine which of the three models is most appropriate for your data.
