Permutation Test for the Equality of Growth Curve

Abstract

Permutation test, which doesn’t require any assumption for the distribution of the random variable, needs to make a lot of calculations, especially when the number of observations increase. However, the use of these non-parametric method is being extended by the developing of the computer technology. In this paper, we considered the testing of the hypothesis of equal means with the permutation test in the Growth Curve Model, by using the computer program written by us. A real data set, fitting the Growth Curve Model, is used for the program.

Büyüme Eğrilerinin Eşitliğinde Permütasyon Testi

Abstract

Tesadüfi değişkenin dağılımının ne olduğuna ilişkin herhangi bir varsayım gerektirmeyen permütasyon testi, özellikle gözlem sayısı arttıkça çok fazla işlem yapmayı gerektirmektedir. Ancak parametrik olmayan bu yöntemin, son yıllarda bilgisayar teknolojisindeki ilerlemelere paralel olarak kullanımı yaygınlaşmaktadır. Bu çalışmada tarafımızdan yazılmış olan bilgisayar programı kullanılarak, Büyüme Eğrisi Modelinde (Growth Curve Model) ortalamaların eşitliği hipotezinin permütasyon testi ile, test edilmesi incelenmiştir. Uygulamada Büyüme Eğrisi Modeline uyan gerçek veri seti kullanılmıştır.
