A "shape parameter" is a generic term for any parameter that is not a
location or scale parameter. In this case, dfn is the parameter for
the degrees of freedom in the numerator of the expression for the F
distribution (whether it is noncentral or not) and dfd is the degrees
of freedom in the denominator.
