survpred_prcmlpmm: Compute the predicted survival probabilities obtained from the PRC models

Description

This function computes the predictive survival probabilities for the for the PRC-MLPMM(U) and PRC-MLPMM(U+B) models proposed in Signorelli et al. (2021)

Usage

survpred_prcmlpmm(step2, step3, times = 1)

Arguments

step2

the output of summarize_mlpmms (step 2 of the estimation of PRC-MLPMM)

step3

the output of fit_prcmlpmm (step 3 of the estimation of PRC-MLPMM)

times

numeric vector with the time points at which to estimate the time-dependent AUC

Value

A data frame with the predicted survival probabilities computed at the supplied time points
