Nothing
Package for parametric relative survival analyses. It allows to model nonlinear and nonproportional effects using splines (Bspline and truncated power basis). It also includes both non proportional and non linear effects of Remontet, L. et al. (2007) <DOI:10.1002/sim.2656> and Mahboubi, A. et al. (2011) <DOI:10.1002/sim.4208>.
