%description
Multivariable fractional polynomial algorithm simultaneously selects
variables and functional forms in both generalized linear models and Cox
proportional hazard models. Key references for this algorithm are Royston
and Altman (1994)<doi:10.2307/2986270> and Sauerbrei and Royston (2008,
ISBN:978-0-470-02842-1). In addition, it can model a 'sigmoid'
relationship between variable x and an outcome variable y using the
approximate cumulative distribution transformation proposed by Royston
(2014) <doi:10.1177/1536867X1401400206>. This feature distinguishes it
from a standard fractional polynomial function, which lacks the ability to
achieve such modeling.
