摘要
通过对 6批康地肉鸡和 2批康达肉鸡共 112 38只鸡的销售体重、价格和售额资料进行相关回归分析表明 ,体重、价格均与售额呈高度正相关 ,且体重与售额间的相关性更密切 ;体重与价格间一般呈负相关 ;体重、价格和售额 3因素间的复回归方程 ^y =a1+a2 x1+a3 x2
The correlation and regression analysis among body weight, price and sum on sale of broilers by data with 6 batches of Conti and 2 Conda The results showed that boay weight and price had a highly positive correlation with sum on sale,and that of body weight with sum on sale was higher Correlation of body weight with price is negative. The regressive equation =a 1+a 2x 1+a 3x 2 by body wight, price and sum on sale may predict the benefit of selling broilers
