查询词典 estimating error

One might attempt to claim that if an event has such a low probability that it does not occur in a very large sample, then actually estimating its probability to be zero will not be a major error.

当一个事件在大规模样本集合中没有出现，属于低概率事件，而实际计算结果为零，这是一个很主要的错误。

The article adopted a new filtering-cloud composing technology used to monitoring drought,analyzed the property of Ts—NDVI characteristic space and the TVDI's indicating drought ability, put forward the TVDI compute model, grade standard, and the impact estimation method. The result indicated: 1 the decade-composed data obtained by the maximum surface temperature principle has better ability than the composed data obtained by the maximum NDVI on monitoring drought; 2 in the Ts-NDVI characteristic space,the dry side and the wet side almost are horizontal lines when the NDVI is on the small side, the temperature difference is about 45℃; 3 the TVDI has inequable level on monitoring drought as its value, the less TVDI indicates without drought occurrence, the bigger TVDI shows the drought certainly happened, the unsure drought conclusion mainly comes from the middle TVDI; 4 the monitored results of Sichuan hot-drought in 2006, obtained by the remote sensing and by the climate index, are basically consistent, the estimating error on the bearing drought crop area and on the drinking trouble population is within 10%.

采用了干旱监测合成滤云新技术，分析了Ts—NDVI特征空间属性和TVDI指数干旱监测能力，提出了四川伏旱TVDI计算模型、分级标准、和影响评估方法，结果表明：1按最大地表温度原则得到的旬合成数据比按最大植被指数原则得到的旬合成数据具有更强的旱情监测能力；2在Ts—NDVI特征空间中当NDVI较小时干湿边几乎同为水平直线，两者相差约45℃；3TVDI指数因其大小不同而对旱情的监测能力也不一样，较小时说明没有干旱发生，较大时则一定有干旱发生，中间段对干旱的监测具有不确定性；42006年四川伏旱遥感监测与气候监测结果基本一致，农作物受旱面积与饮水困难人口数估算误差在10%以内。

In this paper, two-stage Generalized Linear models are developed to estimate the outstanding claims reserve in Non-life insurance. The models are based on the PPCI methods, estimating the claim number and payments per claim incurred respectively to obtain the estimate of OCR and prediction error.

本文以非寿险业务未决赔款准备金估计的确定性方法－PPCI法的思想为基础，分两阶段建立广义线性模型，分别对索赔次数和已发生每案赔付额进行估计，进而得到未决赔款准备金的估计值，并对模型的预测误差进行估计。

In this text, we discuss the method of estimating parameter that the density of explains variable of having measurement error is not abridge, we inquire the covariance of y and e^ and we can get a formula as follows

A new symbol-constrained joint source-channel decoding algorithm for VLCs is presented.By constructing double-tree VLCs sources,the propagation-error problem is evidently alleviated.Meanwhile,by applying symbol-constrained method to MAP algorithm,not only the a priori probability of VLCs sources is efficiently utilized,but also the Symbol Error Rate is reduced enormously.

提出了一种新的针对不等长编码信源的符号约束MAP联合译码算法，利用VLCs双树信源的构造方法，有效地抑制了VLCs的错误扩散；同时，通过将"符号约束"的思想应用于最大后验概率译码算法，不仅充分利用了信源先验信息，而且极大地降低了误符号率。

For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time.

新冲模在指定的冲压设备上投入使用至失效报废的整个寿命过程中，其合格冲件误差的主导部分固定不变即所谓固定误差。其大小就是新冲模第一次刃磨前冲制的合格冲件的偏差，也即冲模的初始误差，而此时的冲模具有初始冲压精度。
