I've been using Cochran's Test to check for outlying variance.  I noticed that
the degrees of freedom that are calculated and output are incorrect.  The author
has forgotten to take into account that df=n-1 and appears to have just left
df=n.  n=# samples per treatment and in the case where n is unequal across
treatments, I believe that the average samples per treatment can be calculated,
then minus 1.
