Dear list
I would like to compute a Mantel-Haenszel chi-square in which the
matching variable is a continuous variable. The MH chi-square is
used to assess the relationship between two categorical variables at
each level or strata defined by a third variable. Specifically I
would like to know if there is a straightforward way to divide the
matching variable into levels, in which each level has a minimum of
20 cases. Any information would be greatly appreciated.
Why? What makes you think matching would be valuable? (...or even
valid, for that matter.)
Thanks in advance
Barth
