coxmcem.mixed.initialize: Initialization for Mixed-Level Meta-Analysis T Frailty Proposal

Description

Returns patient-level starting values for the multivariate T proposal.

coxmcem.mixed.initialize(
		   coxme.formula,
		   phmm.formula,
		   data,
		   init.coef,
		   init.vcov)

coxme.formula

Formula for coxme

phmm.formula

Formula for phmm

data

Patient-level data frame

init.coef

Supplied vector for fixed effects

init.vcov

Supplied matrix for frailty variances

List of mean, Sigma (location and scale of T) and beta, D, the fixed and variance parameters.

First tries coxme, but if estimation is not possible reverts to phmm.
