Factor Analysis Scores in a Multiple Linear Regression Model for the Prediction of Carcass Weight in Akkeci Kids

Abstract

Keskin, S., Daskiran, I. and Kor, A. 2007. Factor analysis scores in a multiple linear regression model for the prediction of carcass weight in Akkeci kids. J. Appl. Anim. Res., 31: 201–204.

In this study, the relationships between carcass weight and 10 body measurements (slaughter weight, withers height, body length, chest depth, chest width, chest circumference, leg circumference, leg width, leg length and rump width) were examined through factor and multiple linear regression analyses. It was observed that three factors e.g. Form, Circumference and Wideness had significant effects on carcass weight and these factors together accounted for 83.9% of variation in carcass weight.

Key words:

• Body measurements
• communality
• eigenvalues
• rotation
• determination coefficient
