A note on formulae for CMH statistics for JAR data

Cochran–Mantel–Haenszel (CMH) test statistics can be used to compare products rated on JAR ‘just about right’ scales and for similar categorical data. In this note we consider the case of paired or related data. The simplified statistics we give allow ‘by hand’ calculation when the data set is small. We also give an R package for larger data sets or for when the user is not interested in ‘by hand’ calculation.
