title: A two-level cross-sectional model using grafted polynomials.
abstract: A new statistical model is proposed for the analysis of hierarchically structured cross-sectional growth data, especially for where measurements are made over long age ranges. The model combines a two-level model with grafted piecewise polynomials, to make efficient use of available data.
