get_Fstat_ddf function

Compute denominator df for F-test

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)

Arguments

• nu: vector of denominator df for the t-statistics
• tol: tolerance on the consequtive differences between elements of nu to

Returns

the denominator df; a numerical scalar

Details

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.
