DIstributional Regression for Times To EvEnt

Description

This package includes regession methods for right-censored response variables. It allows for the estimation of distributional regression methods with semiparametric predictors, including, for example, nonlinear, spatial or random effects. The distribution of the response can be estimated with expectiles, quantiles and mode regression. Censored observations can be included with accelerated failure time models or inverse probability of censoring weights.
