In chjackson/flexsurv-dev: Flexible Parametric Survival and Multi-State Models

flexsurv

The flexsurv R package for parametric survival and multi-state modelling.

Key features

• Parametric models for time-to-event (survival) data. Data may be right-censored, and/or left-censored, and/or left-truncated. Several built-in parametric distributions are available, including a very flexible model based on splines (Royston and Parmar).

• Any user-defined parametric model can be employed by supplying R functions defining the distribution.

• Covariates can be included using a (log-)linear model on any parameter of any distribution. This typically defines an accelerated failure time or proportional hazards model.

• Multi-state models for continuously-observed data can be defined by piecing together transition-specific parametric models of any kind. (For intermittently-observed data, see instead the msm package.)
