Hi,
Does anyone have experience running Mahalanobis matching using psmatch2 in Stata with a large sample? I am matching about two million observations based on six matching criteria, and Stata has been running for nearly a week. Nearest neighbor PSM using psmatch2 only took 7.5 hours, and I'm worried something is wrong. Thank you in advance!
