get_Fstat_ddf {pbkrtest} | R Documentation |
Compute denominator degrees of freedom for F-test
Description
From a vector of denominator degrees of freedom from independent
t-statistics (nu
), the denominator degrees of freedom for
the corresponding F-test is computed.
Usage
get_Fstat_ddf(nu, tol = 1e-08)
Arguments
nu |
vector of denominator degrees of freedom for the t-statistics |
tol |
tolerance on the consecutive differences between elements of nu to determine if mean(nu) should be returned |
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.
Value
the denominator degrees of freedom; a numerical scalar
