## What is the use of panel data?

Panel (data) analysis is a statistical method widely used in **Social science, epidemiological, and econometric analysis of two-dimensional (usually cross-sectional and longitudinal) panel data**. Data is usually collected over time with the same individuals, and regressions are run on both dimensions.
