From a vector of denominator df from independent t-statistics (nu
),
the denominator df for the corresponding F-test is computed.
get_Fstat_ddf(nu, tol = 1e-08)
vector of denominator df for the t-statistics
tolerance on the consequtive differences between elements of nu to
the denominator df; a numerical scalar
Note that if any nu <= 2
then 2
is returned. Also, if all nu
are within tol of each other the simple average of the nu-vector is returned.
This is to avoid downward bias.
