Hi all,

I'm hoping to be able to get some guidance on a work-around for the repeated time values within panel error in Stata. In short, I'm working with a panel data set of 162 countries, for which I'm hoping to be able to run fixed effects on using both a time and panel id dimension. The time FE aspect is fine, as the sample is nicely balanced across 16 years. However, I've been hoping to construct a FE specification on regional indicators i.e. at the continent level. This has not so far been possible due to the repeated time values error. FE's at the country-level is too granular and dampens a lot of the variation in my data.

I'm aware of a less elegant solution which would be just to run a regression on a set of dummy regional (continental) indicators i.e. Asia, North America etc. However, I was hoping to find a tidier method that would allow for the xtreg fe approach to be used, for the added benefit of continuity throughout my analysis but also the suppression of output coefficients for the FE variables.

If anyone has any tips on getting Stata to work with a regional indicator type variable that comprises a number of the same time-variables (here year) across different individual panels, I would be greatly appreciative!

Many thanks,

Scott
