估计

We also study the ANOVA estimation with QR decomposition.

本文同时讨论了QR分解在另外一种估计方法，即ANOVA估计中的应用。

The thesis tends to investigate the establishment of the insurance cycle score and business cycle of the premium of new business. We utilize six kinds of different insurance of new business to be our investigate object, that including ordinary life insurance, group life insurance, individual health insurance, group health insurance, personal accident insurance and group accident insurance. Besides observing fluctuate of the firsthand information, we used the maximum likelihood estimation to estimate the unknown parameter of Markov switching models. Try to cognizance the peak and the trough of business cycle.

本研究在探讨保险新契约之保费的景气循环状况与景气分数的制定，其中我们利用六种不同的保险新契约保费当研究对象，包括个人人寿保险保费、团体人寿保险保费、个人健康保险保费、团体健康保险保费、个人伤害保险保费和团体伤害保险保费，除了观察原始资料的波动外，亦采用最大概似估计法来估计马可夫转换模型的未知参数，尝试著去认定景气循环的高峰与谷底。

But the direction of position line error is overlooked in the textbook, with the result that the formula of standard error of transferred position line and running fix is mistaken.

但是，由于都忽视了船位线误差的方向性，因而引出的转移船位线误差估计的公式是错误的，由此得到的移线船位的精度估计公式也是错误的。

This demonstrates that it is necessary to carry out variance-covariance component estimation for the double-differenced GPS observables.

结果 两种方法估计的方差－协方差阵都与常用的先验协方差阵有明显区别；两种方法估计计算结果非常接近。

Computer simulations show that the performance of proposed method is better than that of conventional oversampling methods, and it is robust to over-estimated channel order.

仿真和分析显示该方法的性能优于传统的过采样盲信道估计方法，且对信道阶数过估计不敏感。

The performance of this method is better than that of conventional oversampling methods, and it is robust to over-estimated channel order.

该方法性能优于过采样信道估计方法，且对信道阶数过估计不敏感。

Preservationists in Iowa reckon they are losing 1,000 barns each year.

爱荷华的保护主义估计他们每年将失去1000个谷仓。2007年的农业普查是第一次对谷仓进行追踪；下一次估计要到2012年。

Simply assuming that under different conditions, gene expression levels have three regulation states, i.e., up-regulation, down-regulation and non-regulation states, we can probabilistically establish a model of gene regulation states to compute gene regulation probabilities under different conditions.

简单假设在两种不同的实验条件下被调控的基因表达水平表现为三种调控状态，即上调控状态、下调控状态和非显著调控状态，我们使用概率统计方法对基因调控状态进行建模。在该模型的基础上，我们应用三种参数概率估计方法对基因调控概率进行估计。

Then five methods to estimate interest rates of government bonds are comparative analysized. The implied term structure of Chinese bonds interest rates is estimated by the Nelson-Siegel model. Samples consist of spot rates with maturities of 3-month, 6-month, 1-year, 2-year, 3-year, 4-year, 5-year, 7-year and 10-year. Through principal components analysis, at least two factors are needed to capture the dynamics of the interest rates.

然后通过比较分析5种建立国债利率曲线的方法，采用Nelson-Siegel模型估计了中国的国债即期利率曲线，并取用估计出来的3个月、6个月、1年、2年、3年、4年、5年、7年、10年期的即期利率数据做样本，进行相关系数分析和主成分分析，发现至少需要两个因素才能较好的描述中国国债利率曲线的变动。
