Definition of panel data

Answer 1

Panel data, also known as longitudinal data or cross-sectional time series data, is a type of observational data where multiple observations or measurements are taken on the same subjects over a period of time. Each subject in the panel is observed at multiple points in time, allowing researchers to analyze changes and trends over time for each subject. Panel data is commonly used in fields such as economics, sociology, political science, and public health to study the effects of various factors on outcomes or behaviors.
