I recently came by a post that states in panel data with small time dimensions the stationarity issue is not present, is this true? can anybody provide a source for this?
- I'm working with a panel data set for 10 states over 11 years, with variables: unemployment, poverty rates, age controls in (%) and minimum wages.
Should I bother trying to test for unit roots? if so what tests would you recommend? I am using R and having difficulties trying to find and understand some tests used in panel data sets.
