Effects of influential points and sample size on the selection and replicability of multivariable fractional polynomial models

BACKGROUND: The multivariable fractional polynomial (MFP) approach combines variable selection using backward elimination with a function selection procedure (FSP) for fractional polynomial (FP) functions. It is a relatively simple approach which can be easily understood without advanced training in...
