Obtain the Adjusted Kenward-Roger degrees of freedom

Obtains the adjusted Kenward-Roger degrees of freedom and F statistic scale parameter. Used in h_df_md_kr() or h_df_1d_kr.

Usage

h_kr_df(v0, l, w, p)

Arguments

v0

(matrix)
unadjusted covariance matrix.

l

(matrix)
linear combination matrix.

w

(matrix)
covariance matrix of the estimated covariance parameters.

p

(matrix)
P matrix from h_get_kr_comp().

Value

Named list with elements:

• m: numeric degrees of freedom.

• lambda: numeric F statistic scale parameter.
