[The multivariate canonical discriminant analysis between physical growth and nutrition status of children and youth]

This paper is on studying the relationship between physical growth and nutrition status of children and youth by using multivariate canonical discriminant analysis. 3,790 boys and girls of 7-19 yrs of age were classified into four groups according to the height-for-weight method. Then, by using seven physical measures as predict variables, canonical discriminant functions were set up for boys and girls respectively. The backward substitutional test showed that the coincidence ate was quite high, 90.90% for boys and 92.47% for girls respectively. The susceptibility of various physical measures in reflecting children's nutrition status was analysed, and the practical use of these discriminant functions was discussed.
