DID in Panel data with Stata 17.

[Waqas Younis]

I have two groups of countries. My treatment group is ( 27 countries of European Union) and my control group is 15 "other countries". My data is panel data from 2004 to 2022.... the policy started in 2014 (mean policy is implemented by treatment group in 2014 and till 2022).... I want to check the impact of "policy" on my "variable of interest" during pre-period (2004-2013) and post period (2014-2022) for treatment group (european union countries) and control group (other countries).. I want to apply Difference in Difference technique on my panel data.. i have "1" dependent variable and "5" independent variables. How i can perform all the analysis of DID technique applied in panel data in stata 17? please guide me step by step (stata commands) including all tests which should i perform on data. thanks for cooperation.
