参数估计

The data were measured in 232 permanent sample plots. With the data of permanent sample plots, the parameters of transition probability and ingrowth models were estimated, and some models were compared and partly modified.

通过大量的省级固定样地资料，对林分生长转移概率模型和进界生长模型进行了参数估计，并对模型进行了比较和修正。

Such as dynamic model, parameters estimation, interposition, application steps and so on.

第五章，小批量生产过程中的使用统计质量控制方法所面临的突出问题是如何充分利用有关过程的信息（包括客观的历史数据和主观的经验与判断），本章提出了应用贝叶斯预测理论的动态质量控制方法，详细研究了这一方法的动态建模、参数估计、模型干预及实施步骤，进行了计算机仿真试验和应用研究。

By using the observed data, some nonparametric estimating methods, such as jackknife and bootstrap, were used to estimate the numbers of species in the community.

用实测数据对物种数目的非参数估计法的评价表明，用自助法所得到的物种估计数，与客观实际更为接近。

Methods:The mathematical model created by Kipper,and the regression coefficients of age,period and cohort were calculated by using triangle matrix.

采用Kupper数学模型，用矩阵的三角分解法求解，对三因素的各个亚层成分效应大小的定量参数估计。结果：1970～1994年栖霞市胃癌死亡率前10年上升后15年呈平稳下降趋势。

Meanwhile, the estimated parameters with equation constrains are derived by using Lagrange multiplier law.

同时利用Lagrange乘数法导出了带有等式约束的最小方差投资组合的参数估计。

In order to improve the monitoring precision and resolution of tropospheric zenith delay, the hybrid approach, using a batch least squares estimator but parameterizing the zenith delay by a linear spline with knots at 30-minute intervals and treating the knots as a Gauss-Markov process, is employed to deal with the tropospheric zenith delay.

为了提高对流层天顶延迟的监测精度和分辨率，我们采用了分段的参数估计和随机过程相结合的估算方法来处理对流层延迟，由此获得了分辨率分别为2 h和30 min，精度好于1 cm的天顶延迟量。

The estimation on the regression coefficients of linear model is one of the most basic content.

线性模型的统计分析理论相当丰富，而参数估计问题则是其中最基本的内容之一。

This method uses periodic sequences of different magnitudes as inputs to extract a linear subsystem so that the set theory, parameter estimation, optimization, pole zero separation, can be applied.
