I get the idea that Tomas would like to keep the multivariate when it's
actually referencing multivariate stats. The idea of the rename was to
allow future expansion of the code to perhaps allow creation of stats on
expressions, which is not multivariate. If you've found multivariate
reference in an area that should be generic to extended statistics then
that's a bug and should be fixed.
I found a few of these and listed them during my review.
