In jlctree: Joint Latent Class Trees for Joint Modeling of Time-to-Event and Longitudinal Data

Description

Computes the likelihood ratio test statistic. Not to be called directly by the user.

Usage

get_lrt(f1, f2, data, stable = TRUE, cov.max = 1e+05)

Arguments

f1	a two-sided formula of the fitted survival model, without the longitudinal outcome in the right side of the formula.
f2	a two-sided formula of the fitted survival model, same as f1 but with the longitudinal outcome being the first covariate on the right side of the formula.
data	a data.frame containing the covariates in both f1 and f2.
stable	a parameter, see also jlctree.control.
cov.max	a parameter, see also jlctree.control.

Value

The likelihood ratio test statistic.
