`censrec` | (numeric) | 1=dead, 0=censored |

`rectime` | (numeric) | Time of death or censoring in days |

from a regression model developed by Sauerbrei and Royston (1999). | ||

German Breast Cancer Study Group, 1984-1989. Used as a reference
dataset for the spline-based survival model of Royston and Parmar (2002),
implemented here in `flexsurvspline`

. Originally provided with
the `stpm`

(Royston 2001, 2004) and `stpm2`

(Lambert 2009, 2010)
Stata modules.
