I am facing some problem when analysing my data set. I have
a 1:2 case-control pairs data set. I can't decided myself
to which tests(McNemar or Mantel-Haenszel) i have to performed
to analyise my data. Can anybody help me whether McNemar test
can be applied to 1:2 case-controlpairs data set or it is only
applied to 1:1 case-control pairs dataset.
Is it any wrong with me if i applied Mantel-Haenszel test in
mydata set. Some of the statistical books writing Mantel-Haenszel
test can be applied to stratified data but not for matched data.

-mcc- only handles 1:1 matched data. You can use -clogit-
(conditional logistic regression) for any matching ratio,
even varying ratios. -clogit- also lets you adjust for
potential confounders.
Example:
webuse lowbirth.dta
clogit low smoke , group(pairid) or
Hope this helps
