nested anova not giving expected results
...I'm a little
bit stumped with respect to the calculation of the F statistics in nested
anovas in R. If I understand correctly, the F statistic for the
among-subgroups but within groups hypothesis is calculated as
MS_subgroups/MS_error, while the F statistic for the factor is calculated as
MS_factor/MS_subgroups (I'm getting this from Sokal & Rohlf's _Biometry_).
However, as I understand the output from R, it calculates the F for the
factor as MS_factor/MS_error, which can significantly change the results.
As an example, I took the values from Sokal & Rohlf's example on...
