Subject: Creating the group(matching) variable for clogit









Good morning,





I am using clogit and need to create a group(matching) variable for cases with controls.  There are several matching criteria which have all been categorised: sex, country, time of survey, age, and fasting status.





How would I go about creating a group variable to match cases and controls based on the listed matching criteria?





Many thanks,

Neil Murphy
