雷州山羊成年母羊体重及体尺指标的回归分析

The Regression Analysis Between Body Weight and Body Measurements of Leizhou Manny Goat

本文采用逐步回归的方法对随机抽测的96只雷州山羊成年母羊的体重和8个主要体尺指标进行回归分析,得到雷州山羊成年母羊体重和主要体尺指标的最优回归方程为Y^=37.400+0.140X1+0.346X4+1.215X6P<0.01。明确了雷州山羊成年母羊体重与体尺指标的关系,为今后雷州山羊的选育工作提供参考。

By the stepwise regression method the regression analysis was conducted between the body weight and8body measurements of96Leizhou manny goat sampled randomly and the optimum regression equation was obtained as follow,Y^=-37.400+0.140X 1 +0.346X 4 +1.215X 6,P <0.01.The relationship between the body weight and body measurements has been made certain and the result could be used as a referrence information for selection and breeding Leizhou goat in future.
