plot_deviance_residuals: Function to plot the deviance residuals of a fitted coxph...

In benjamin-w-campbell/coxtools: Tools for Cox Proportional Hazards Models

Description

This function assists the user in assessing model performance according to deviance residuals. The two plots produced are designed to help the analyst understand which observations are poorly predicted and how model performance fairs with respect to timing of events.

Usage

plot_deviance_residuals(coxph_fit = NULL)

Arguments

coxph_fit

The output from a fitted "coxph" call.

Value

A ggplot2 object presenting the deviance residuals for the model.

Examples

library(survival)
data("heart")
# Coerce from factor
heart$transplant <- as.numeric(heart$transplant)
# Rescale age
heart$age <- heart$age+48
coxph_fit <- coxph(Surv(start, stop, event) ~
              age + transplant +surgery,
             data = heart,
             x = TRUE)

plot_deviance_residuals(coxph_fit = coxph_fit)
