Additiv Two-Way Hazards Modelling of Right Censored Survival Data.

The package offers a fitting of smooth varying coefficients in an additiv two-way hazard model. A one-way hazard model can also be fittied with supplementary functions. Nonparametric penalized spline (p-spline) fitting is proposed. In the two-way case two alternativ models can be analized: In the first one a non periodic calendar time, like the calendar year, is considered as a second time scale (additionaly to the survival time), and as a spline basis truncated polynomial functions are chosen. In the second model a periodic time scale, like a season of year, is additionaly considered, and as a spline basis the b-splines are selected. In the one-way case the user can choose between these two alternative penalized bases.
