h_get_empirical: Obtain Empirical/Jackknife/Bias-Reduced Covariance

In mmrm: Mixed Models for Repeated Measures

Obtain Empirical/Jackknife/Bias-Reduced Covariance

Description

Obtain the empirical or Jackknife covariance for \beta. Used in mmrm fitting if method is "Empirical", "Empirical-Jackknife" or "Empirical-Bias-Reduced".

Usage

h_get_empirical(tmb_data, theta, beta, beta_vcov, type)

Arguments

tmb_data	(mmrm_tmb_data) produced by h_mmrm_tmb_data().
theta	(numeric) theta estimate.
beta	(numeric) beta estimate.
beta_vcov	(matrix) covariance of beta estimate.
type	(string) type of empirical method, including "Empirical", "Empirical-Jackknife" and "Empirical-Bias-Reduced".

Value

Named list with elements:

• cov: matrix empirical covariance.

• df_mat: matrix to calculate Satterthwaite degree of freedom.
