I have split my sample into three time periods (pre-GFC, GFC, post-GFC) when reporting summary statistics.
I am seeking to add stars to the "mean" columns in my summary statistics output.
I want these stars to represent the level of significance from testing for differences in means between the following time periods:
- Pre-GFC panel: no stars or tests
- GFC panel: pre-GFC vs. GFC
- Post-GFC panel: post-GFC vs. pre-GFC
I would really appreciate any help I can obtain on this forum. Thank you.
