This paper proposes a new non‐parametric procedure to estimate age‐dependent reference ranges based on Tibshirani's AVAS (additivity and variance stabilization) procedure for non‐parametric estimation of transformations for regression. Several examples are given to illustrate the flexibility and applicability of the proposed method; these include alkaline phosphatase in girls, and foot length and head circumference during gestation. © 1998 John Wiley & Sons, Ltd.
