ADAPTING HELLWIG'S METHOD FOR SELECTING CONCOMITANT VARIABLES UNDER A CERTAIN GROWTH CURVE MODEL Mirosława Wesołowska-Janczarek, Monika Różańska-Boczula Department of Applied Mathematics and Computer Science, University of Life Sciences in Lublin, Głęboka 28, 20-612 Lublin, Poland, e-mail: monika.boczula@up.lublin.pl |
This paper presents an application of Hellwig's method for selecting concomitant variables under a growth curve model, where the values of the concomitant variables change over time and are the same for all experimental units. The authors present a simple adaptation of the growth curve model to the multiple regression model for which Hellwig's method applies. The theoretical considerations are applied to the selection of significant concomitant variables for raspberry fruiting.
