 Description: Algorithm to select variables and functional forms through 
   fractional polynomials in regression models (Generalized linear models 
-  and Cox). This package also
-  implements various extensions of the original algorithm (sigmoid functional 
-  forms) and provides estimation and visualisation of non-linear effects. 
-  A key reference is the book by Royston and Sauerbrei, 2008.
