Subject | st: Using clogit After psmatch2 |
Date | Sun, 21 Nov 2010 20:22:07 -0600 |
I want to use clogit after creating a 1:1 nearest neighbor match using psmatch2. However, I am unsure how to identify the matched treated and control observations so that I can specify the group(varname) option in clogit. For example, in the lowbirth dataset (webuse lowbirth) the variable pairid is used as the group(varname) option: clogit low lwt smoke ptd, group(pairid). And the pairid variable is sturctured like this: pairid low age lwt smoke ptd ht ui race1 race2 race3 1 0 14 135 0 0 0 0 1 0 0 1 1 14 101 1 1 0 0 0 0 1 2 0 15 98 0 0 0 0 0 1 0 2 1 15 115 0 0 0 1 0 0 1 Therefore, my question is: How do I create a variable like pairid after using psmatch2? Thanks in advance for your time and assistance.
