This utility can be used to apply McNemar chi square test, to test the association between two dichotomous variables. (Matched pair design; 1:M matching ratio of cases to controls; M <= 4)
(For M > 1, chi square is calculated using Miettinen (1970) and Pike and Morrow (1970) extention)
Formula used and other details
Number of controls per case in the matched unit (1:M)
Required
1: M pairing. You can have maximum of 4 controls per case (1:4 matching)
Observed values in your study.
