| Subject | st: Generating a matched pair sample for a case-control study |
| Date | Fri, 7 Dec 2012 12:27:03 -0500 |
Hello, I need to generate a sample of controls matching the age frequency distribution of the cases. Matching will be 1 (case) to 2 (controls). There are a total 63 cases that have already been randomly selected, and I need to match them with 126 controls from a pool of subjects. Cases have a 30-day hospital readmission, controls do not. I currently have all the cases in a Stata file. The pool for selecting matched controls is an Excel file that I can easily copy and paste into Stata. Is there a Stata command to generate a sample of matched pairs based on the age frequency distribution for cases that have already been randomly selected? Thanks for the help, Paul * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
