Sunday Stata Tip | Merging 1:1
The first of 2 videos on merging in Stata. Here I talk about how to merge 1 row from a secondary dataset onto a single row in the dataset already in use.

The question I'd like answered is when to merge 1:1 or 1:m or m:1. And what to do if you have multiple key variables.

So a longer merge vid with multiple examples is needed.
