ertte: Exposure-Response Tools for Time-to-Event Models

Provides estimation tools for exposure-response models of time-to-event endpoints based on the 'survival' package: parametric accelerated failure time model fitting and prediction with AIC-based distribution selection, stepwise covariate modelling, and simulation-based visual predictive checks. Tested and supported for the exponential, Weibull, log-normal, and log-logistic distributions. For a model-agnostic mini-language to visualise exposure-response models (including those fitted with 'ertte'), see the companion package 'erplots'.
