Hi,

I'm using Stata 16 for my analysis. I've run the pstest command to obtain results for the balancing property. I'll be glad if you aid me in interpreting the results. Specifically;
1. How balanced is the match between the treated and control groups.
2. The significance of the t-test.

Below is ts the command used and results generated from Stata.
