Colleagues, I am trying to write a script for the Mantel Haenszel test.
For the MH test, the test statistic is chi-square (MH) = (W-1) * r^2 Where W = sum of the case weights. This is straight forward. I'm having difficulty with r^2. The r^2 is the squared Pearson correlation between row and column variables. Can anyone give me an example of the code which calculates the squared Pearson correlation between row and column variables? I am at a loss on how to do this. All the best, Thomas Subia ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
