kmatch - matching weights

[Marie-Lien Gerits]

Hello everyone,

I am using the kmatch command to perform Epanechnikov kernel propensity score matching (with bandwidth). However, I do not understand how the matching weights (_KM_mw) in my output are calculated. Can someone help me? Thank you in advance!

Kind regards,
Marie-Lien
