应用多项式回归模拟鸡产蛋曲线的研究

STUDY ON APPLYING POLYREGRESSION TO SIMULATING LAYING CURVE

用多项式回归配合曲线，证明三次曲线具有较好的适合度，复相关系数（均在０．９５以上（Ｐ＜０．０１）。从配合曲线计算各月的产蛋量与原测数据相似较好。

Applying polyregression to curve fitting,three regression line proved out to fitness. The multiple correla-tions R are over 0. 95(p<0. 01). With the curve fitting,there are nicely similarity between the val-ue of theory and actuality in the mouthly egg production.
