I'm trying to do nearest neighbor matching in STATA 15 for Windows, but I'm just looking for matches, not estimating treatment effects. I have observations on counties like this:
AREA EMPLOYMENT AVG WAGE MIN WAGE
18472 5700 14 10
19320 6390 12 8
Ideally, I'd like to create a new variable that is just the address of the nearest neighbor based on employment, average wage, and min wage of that county, without having a dependent or treatment variable. A distance-to-nearest neighbor variable would also be welcome.

Is there an option to do this within the teeffects nnmatch command? Or there an alternative method I'm not aware of for nearest neighbor matching?
