Perform the McNemar test on a 2x2 matrix

File Information
Description	In statistics, McNemar's test is a non-parametric method used on nominal data to determine whether the row and column marginal frequencies are equal. It is named after Q. McNemar, who introduced it in 1947. It is applied to 2x2 contingency tables with a dichotomous trait with matched pairs of subjects. This is only a simply function to perform the McNemar's chi-square with Yates'es correction. The function requires Statistics Toolbox because calls CHI2INV and CHI2CDF function.
Required Products	Statistics Toolbox
MATLAB release	MATLAB 7.3 (R2006b)

02 Jul 2007	Sarah Inowe	Hey Mr. Cardillo. What I am seeing is that you are doing some ?refried? of functions already published. Why you do not propose something really new?
20 Oct 2009	Skynet	Thanks for this file. I used it to confirm the results of my own calculations. Note that errors that you throw probably shouldn't use the term "Warning" in the error text, because that is misleading.
