Percentile Smoothing Using Piecewise Polynomials, with Covariates

A nonparametric procedure for the joint smoothing of a series of percentile curves is presented. It allows separate curves to be fitted over contiguous age ranges, constraining them to join smoothly. Covariates can be incorporated, thus allowing efficient estimation simultaneously for subgroups. Full description
