| clogit {survival} | R Documentation |
Estimates a logistic regression model by maximising the conditional
likelihood. Uses a model formula of the form
case.status~exposure+strata(matched.set).
The default is to use the exact conditional likelihood, a commonly
used approximate conditional likelihood is provided for compatibility
with older software.
