非对称养分效应模型参数估计的一种优化回归组合法

Method for estimating asymmetrical nutrient effect model parameters: an optimization regression combining method

摘要: 在现有文献研究的基础上，对非对称养分效应模型参数估计问题又作了进一步探讨，指出了现有文献给出的参数估计方法存在的局限性和不足。在此基础上，研究提出了一种新的参数估计方法——优化回归组合法，该方法不仅克服了现有文献给出的参数估计方法之不足，而且经示例计算表明，该方法具有较高的拟合精度。

Abstract: The paper makes further research on estimating the parameters of the asymmetrical model describing effect of nutrient based on present literature, points out faultiness of the parameters estimating method in present literature, provides a new method for estimating parameter,i.e, an optimization regression combing method. The method not only avoids the above faultiness but also has a precise fitting degree.
