ON THE USE OF DETERMINATION COEFFICIENT TO DESCRIBE GOODNESS OF FIT OF ASSESSED GROWTH CURVES Miroslawa Wesolowska-Janczarek Instytut Zastosowań Matematyki, Akademia Rolnicza w Lublinie, Akademicka 13, 20-934 Lublin, Poland |
In the paper a way of using the well-known determination coefficient for growth curves, assessed by the multivariate Potthoff-Roy's method, is proposed. Modified definitions of determination coefficients for each of the object levels and of the mean determination coefficient are given. The latter characterizes goodness of fit for all curves that are calculated by the given method. The problem is illustrated by two examples on real data.
determination coefficient, mean determination coefficient, goodness of fit, growth curves.
