Im doing a research that includes data for 11 years ...we have to compare how the ppp ownership has impact cost of company by comparing when organization was public owned with ppp ... we have time seria data what statistical test do you suggest to use?
After conducting stationarity tests of the variables, you could use panel data methods (especially panel OLS, fixed-effects, random-effects, and VEC (if needed).
You may start by using difference-in-differences method for comparison of two groups of companies across time.
The difference-in-differences method is a quasi-experimental approach that compares the changes in outcomes over time between a population enrolled in a program (the treatment group) and a population that is not (the comparison group). It is a useful tool for data analysis.
