Nov 16, 2022 · Stata 14 now provides panel-data parametric survival models. Examples of survival outcomes in panel data are the number of years until a new recession occurs for a group of countries that belong to different regions, or weeks unemployed for individuals who might experience multiple unemployment episodes. We often have data where variables have been measured for the same subjects (or countries, or companies, or whatever) at multiple points in time. These are typically referred to as Panel Data or as Cross-Sectional Time Series Data. We need special techniques for analyzing such data, e.g. it would be a mistake to treat 200 individuals measured ...Two elements are immediate. First, the panel structure is crucial here. For each panel, we must identify the first (or perhaps last) occurrence of a state, say, state == 1. To experienced Stata users, this should suggest that you use by varlist: , here by id:.

Here is an example on how you create a dummy in a panel data and then collapse those dummy to the parent unit-of-observation making the dummy 1 if the parent unit-of-observation was 1 in any time period. Then merge the parent unit-of-observation level data back to the panel data. * Example generated by -dataex-.
