It does not mean that Stata converst the unbalanced panel into a balanced one, but that unbalancedness is not an issue that you should be worried about; - Stata will automatically omits observations with missing values in any of the variables ... Nov 16, 2022 · 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.
