摘要
本文讨论了求二次回归方程与真二次曲线的最大偏差及其可靠度的方法,并用于测定小麦产量与硫铵投入量的真正边际关系的精度,给出在满足最大收益前提下,小麦估计产量与真正产量的最大偏差及其可靠度。
Taking the way of getting the maximum deviation and its reliability of quadratic regression equation and quadratie curve, one can determine the precision of the marginal relation between the estimnte of wheat yield and the amount of the used sulphuric ammonia and the maximum deviation and reliability between the estimated yield and the real one with the prerequisitc of the gleatcst gains.
