Using tsappend with panel data tsappend’s actions on panel data are similar to its action on time-series data, except that tsappend performs those actions on each time series within the panels. To work within panels, a panel variable must have been specified with tsset or xtset. It does not matter which command you use; the two are equivalent.Panel data are a type of longitudinal data, or data collected at different points in time. Three main types of longitudinal data: Time series data: Many observations (large t) on as few as one unit (small N).
