 parameter estimating
 Application of martingale arguments to the regression parameter estimating function show the Breslow (1974) estimator to be consistent and asymptotically Gaussian under this model. Compared with other traditional methods, this control law reduces on-line parameter estimating burden. The 15 L volume provides sufficient biomass to conduct parameter-estimating experiments from a BNR-functioning biomass. This concept is consistent with low-order autoregressive linear models, and is routinely used for parameter estimating.
 Numerical simulation method is suggested in this paper to estimate the parameters of the pipe cost formula. An example is presented, and the result shows that the theory is reliable, the practical procedures are convenient, and all of the three parameters estimated by this new method are more accurate than those by current methods in the sense of least square. 本文将数值模拟原理用于推求管线造价公式．总结出数值模拟相关分析新方法，实例表明，这种方法理论可靠，上机操作简便易行，结果使三参数的估计均具有最小二乘的统计意义．因而，与传统的估算方法相比精度更高，效率更高。 The method by change of variables is usually used to linearize in non linear fitting, and then the linear model is employed in the calculation. But it must be pointed out that in this method the parameter estimates are still not unbiased estimates. For improving the calculating process, the authors use the Newton method to optimize parameters, and, thus, the parameters approximate to unblased estimates and the accuracy of the fitting is raised.

But it must be pointed out that in this method the parameter estimates are still not unbiased estimates. For improving the calculating process, the authors use the Newton method to optimize parameters, and, thus, the parameters approximate to unblased estimates and the accuracy of the fitting is raised. An illustration calculation shows that the proposed method is appropriate to the analysis of ground water level curves. 在非线性拟合中，常采用变量替换的方法使之线性化，再按线性模型处理。但这种方法并非无偏估计。采用牛顿法逐次改进其参数，使之逼近无偏，从而提高曲线拟合精度。实例计算表明，此法用于地下水位的曲线拟合效果显著。 Based on the theory of soomthing, filting, and parameter estimating in modern cybernetics, the mothed of nonlinear system indentification of landside is studied, and its application prospect is also discussed. 基于现代控制论中的平滑、滤波、预测和参数估计理论，研究了滑坡系统非线性识辨的理论及实现方法。分析了该理论的应用前景。 << 更多相关文摘
