Computes the test statistic at the current node. Not to be called directly by the user.

Usage

1
get_node_val(f1, f2, data, lrt = TRUE, ...)

Arguments

f1

a two-sided formula of the fitted survival model, without the longitudinal outcome in the right side of the formula. Only needed when lrt=TRUE.

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 covariates in f2.

lrt
