What is the formula of Pseudo-F statistic in capscale in vegan?
...educed)
(SSTotal-SSFull)/(N - qFull - 1)
(3) R code
## creating Bray-Curtis of Biodiversity data
H.BC <- vegdist(H.Full [,14:211], "bray")
## Distance based redundancy analysis (dbRDA)
m1<-capscale(H.BC ~ GroupSize + Board + MtgStyle + DmStyle + DifView +
VolAuton, SScomp [,14:19], distance = "euclidean", add = TRUE)
### NOTE: pseudo-F values are the same with or without correcting for
negative eigenvalues (although they are different from other programs).
