Estimation of the Egg Albumen Weight in the Japanese Quails using Ridge Regression Method

In this work, Ridge regression method has been used firstly to determine albumen weight from some egg quality characteristic in the Japanese quails. In order to determine albumen weight, a regression equation was obtained using by egg weight (EW), shape index, (SI), albumen index (AI), yolk index (YI), yolk weight (YW), crust thickness (CT), crust weight (CW), albumen height (AH) and Haugh unit (HU). The goodness of fit of the model were determined as R2=0.685 and Adj. R2=0.670. It was that, given the high degree of multicolinearity of the predictor variables, Ridge regression techniques would provide less standard errors than would the Least Square (LS) technique in this research.
