pec (version 2022.05.04)

Prediction Error Curves for Risk Prediction Models in Survival Analysis

Description

Validation of risk predictions obtained from survival models and competing risk models based on censored data using inverse weighting and cross-validation. Most of the 'pec' functionality has been moved to 'riskRegression'.

Functions in pec (2022.05.04)

Special

Drawing bootstrapped cross-validation curves and the .632 or .632plus error of models. The prediction error for an optional benchmark model can be added together with bootstrapped cross-validation error and apparent errors.
