Panel data in stata.

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.2 Answers. Sorted by: 1. 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-.This is pseudo code. Here, you are supposed to use your dataset. If your dataset is loaded into memory, just run the code excluding that line. But then when I ran the code I ended up with only regression results for one of my companies. You should get the same results as with statsby + the DW statistic.Walk through using fixed- and random-effects models in Stata with bank balance sheet quarterly panel data.Link to "Gentle Introduction to Stata"https://www.a...

So basically I understand that in stata, one should utilise XTSET to declare panel data and then xtreg for the regression so for instance: (xtreg dependentvariable independentvariable1 independentvariable2 independentvariable3, fe) The fe at the end is fixed effects but am slightly confused about exactly which variable adding a fe at the end is ...

Answer: 1. Identify the variable of interest and the reference. To fix ideas, we will work with a panel dataset, which may be downloaded from the Stata website: This dataset includes economic data on 10 anonymous companies for 20 years, 1935–54. The panel structure has been specified with xtset.
