(2) pseudo-F formula
We know that PRIMER uses the following formula to calculate the pseudo-F for
a sequential test of significance (equation 4.3, Anderson, Gorley, and
Clarke 2008, Chapter 4. Pg. 129, and based on pseudo-F equation in Legendre
and Anderson (1999), Ecological Monographs vol. 69):
F= (SSFull - SSReduced)/(qFull-qReduced)
(SSTotal-SSFull)/(N - qFull - 1)
