Canonical Correlation Analysis and Its Application in Animal Sciences

In animal breeding researches, generally more than one character or variable are taken for measurement from the same animal. In order to determine the degree and direction of the linear relationships belonging to these obtained measurements, simple correlation analysis is usually preferred by resear...

Research on Comparision of Lactation Curves in Milking Sheep Husbandry

In this study, the lactation records of 204 heads Awassi sheep that of raised at Gözlü State Farm of Turkey were taken as a animal material. The most suitable mathematical model of parameters for Awassi sheep milk curve were determined in this study as (1) Y(t) = atb e(-ct) , (2) Y(t) = a + bt +ctø ...

Use and Comparison of Permutation Tests in Linear Models

F and t-test are generally used to test significance of hypothesis and/or model parameters. Although parametric tests are considerably effective, they can be ineffective when the assumptions needed by model are not provided, which is a usual stuation for many data sets. In this case, permutation te...

Comparison of K-Means and Fuzzy C-Means Algorithms on Different Cluster Structures

In this paper the K-means (KM) and the Fuzzy C-means (FCM) algorithms were compared for their computing performance and clustering accuracy on different shaped cluster structures which are regularly and irregularly scattered in two dimensional space. While the accuracy of the KM with single pass was...
