#1655: Docs for var, std, stderr, samplevar, samplestd have wrong divisor

Component: Other | Version: 0.7.0

The sample (unbiased) calculation for variance uses 1/(N-1), where N is
the number of samples. The docs are reversed for several of the functions,
though not all. The 'tvar' and 'sem' functions have correct
documentation.
Incorrectly states N for sample calculations:
samplevar, samplestd, tsem
Incorrectly states N-1 for full/true calculations:
var, std, stderr

I realize this is a bug report for a version several minor points old, but
it was first in the Google search and should still be corrected in my
opinion.
Thanks!
