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

Abstract 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 tra...
