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). \n\n* Any user-defined parametric model can be employed by supplying R functions defining the distribution.\n\n* 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.\n\n* 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](http://CRAN.R-project.org/package=msm) package.)\n\n\n## Learn more \n\n[User guide (PDF)](https://chjackson.github.io/flexsurv/articles/flexsurv.pdf).\n\n[Guide to multi-state modelling in flexsurv](https://chjackson.github.io/flexsurv/articles/multistate.pdf).\n\n[Full reference manual](https://chjackson.github.io/flexsurv/reference/index.html) for all the package's functions.\n\n[Paper in Journal of Statistical Software (Jackson 2016)](https://www.jstatsoft.org/article/view/v070i08).
