✦ Synopsis

Given a number of developing aspects of the skeletal system that may be used as indicators of maturity, some combination rule is required to produce a single numerical description of skeletal maturity from data on several such indicators. In the RWT system for estimation of skeletal maturity from indicators in the knee, a nonlinear statistical model for graded data is used for this purpose. In the application of a similar model in the FELS system for the hand-wrist, the estimation procedure was extended to include continuous as well as graded indicators. This paper describes the statistical estimation procedure used, with illustrations drawn from the hand-wrist system.
