The parameter of a F distribution, used by Fd-class
Objects from the Class
Objects can be created by calls of the form
new("FParameter", df1, df2, ncp).
Usually an object of this class is not needed on its own, it is
generated automatically when an object of the class Fd is instantiated.
W <- new("FParameter", df1 = 1, df2 = 1, ncp = 0) df2(W) # df2 of this distribution is 1. df2(W) <- 2 # df2 of this distribution is now 2.
