A Guide to Model Selection For Survival Analysis

WebOnce we fit a Weibull model to the test data for our device, we can use the reliability function to calculate the probability of survival beyond time t. 3. R ( t β, η) = e − ( t η) β. Note: t = the time of interest (for example, 10 years) β = the Weibull scale parameter. η = the Weibull shape parameter. WebA straightforward way to calibrate Cox survival models is to use the calibrate function provided by the rms package in R, as in the page that you linked.This package provides a cph method for Cox models that is designed to work with the calibration and validation methods that it provides for several types of regression models..
