摘要
目的 探讨根据已知经验模型建立新的回归方程的方法。方法 根据已知经验模型确定的相关变量关于同一参变量的回归方程 ,消去共同的参变量得到新的回归方程。结果 经实例验证 ,由本文方法可以建立模型和参数实际意义明显、拟合精度较好的头围随身长变化的回归方程。结论 本文方法是建立回归方程的一种有一定理论依据、实用性强。
Objective A method of building new regression equation by the known empirical model was discussed in this paper.Methods A new regression equation was given by eliminating the parameter of the parametric equation which was determined by the known empirical model.Results It could be seen from the example that the regression equation given by the method in this paper and its parameters had the practical significance and better fitted effect.Conclusion The method given in this paper is one of having theoretical basis,more powerful practicality and easy to use on building regression equation.
