What are some ways to create panel data in Stata? - Quora.I have a panel data structure in Stata with gaps. I've used tsfill to expand the data set and this created missing observations for the years that were missing. I've looked at the documentation for tsset and tsfill, but I'm unsure of how to fill in the missing data appropriately for my situation. As always, any help is greatly appreciated!Before we use tsfill command for filling gaps in the given data, we need to tell Stata about the type of data being used in Stata. This could be done by using tsset command. Tsset’s function is to handle time-series setting of a dataset. We can specify that the data in memory is time series by using the tsset command.

In a pooled dataset with heteroskedasticity you should use robust standard errors. This will adjust the standard errors to take account of the heteroskedasticity.
