查询词典 inconsistent estimator

Under CLM, OLS is not only BLUE, but also the minimum variance unbiased estimator, that is, among linear and nonlinear estimators, OLS estimator gives the smallest variance.

在经典线性模型假设下，OLS不仅是BLUE，而且是最小方差无偏估计量，即在所有线性和非线性的估计量中，OLS估计量具有最小的方差。

Unlike unbiasedness―which is a feature of an estimator for a given sample size―consistency involves the behavior of the sampling distribution of the estimator as the sample size n gets large.

无偏性是，给定样本容量n下，估计量的性质；一致性则是，当样本容量n变大时，估计量的样本分布的变化特征。

Two methods( moment estimator ,bootstrap estimator) are presented for estimating the number of rare species by the sampling of quadrats.

利用矩估计和一个稳健估计方法来处理植物学家在林地的地面植被群落调查数据。

Therefore, it is an inconsistent estimator of z.

因此，它是Z的不一致的估计量。

An inconsistent estimator of z.

因此 ，它是 Z的不一致的估计

Then this thesis presents another SLAM algorithm-the Relative Map Filter, The RMF is however disadvantaged by the inability to guarantee consistency of the estimated relative map. The following sections introduce a new navigation filter - the Geometric Projection Filter or GPF. The consistency of the estimated relative map is enforced by the application of the constrained estimator to an inconsistent relative map produced by a standard RMF.

然后介绍了SLAM问题的结构，分析了绝对地图滤波器的性质，介绍另一种解决方法—相对地图滤波器，但是相对地图滤波器产生不一致的相对地图，因此在相对地图滤波器的基础上应用约束估计产生一致的相对地图，这就是几何投影滤波器，从而有效的解决了SLAM问题。

薄膜或纸张表面不干净，裹入灰尘或杂质清除后再行覆膜薄膜有折皱或松驰现象，薄膜卷边换用新膜干燥温度过高，粘合剂表面结皮调整烘道温度，清除结皮胶的粘接力和耐热性不够换用更好的胶水覆膜后起皱薄膜传送辊是否不平衡；薄膜两端松紧不一致或波浪边；调整覆膜机器胶层过厚，溶剂蒸发不彻底，影响了粘度，受压力滚筒挤压，纸张与薄膜之间产生滑动调整覆膜工艺电热辊与橡胶辊两端不平、压力不一致、线速度不等调整覆膜机器覆膜后易变黄胶水中的主体树脂特别是一些增粘树脂或助剂不耐老化，在光、热、紫外线的影响下，发生化学变化，生成有色物质应换用新胶水

The first step was to investigate the academic background of translators who had published the popular science translations in psychiatry. The second was to discovered translation errors which may contribute to the inconsistent terminology translation, attempting to find the relation between each type of translation error and academic background of translators. The third step was to retranslate the inconsistent terminology related to suicide under the framework integrating the psychiatry expertise and the reader-centered translation theory.

本研究具体进行的程序分三个步骤，第一是了解近年来从事精神医学科普书译著的译者学术背景，第二是归纳精神医学科普书译著各种形式的医学专有名词中出现的翻译失误导致译名不一致的因素及各类译者在翻译时出现的翻译失误类型，第三是以整合精神医学专业知识与以读者为中心的翻译理以求译词易解的汉译名词。

We think that inconsistent requirements are inevitable, which can only be reasoned under inconsistent and evolutive environment.

认为不一致需求是不可消除的，只能在不一致的、演化的环境下推理。

In addition to a theory being logically self-referentially inconsistent, a theory can be inconsistent by virtue of itself denying or implying the contrary of one of its justificatory, semantic, or pragmatic presuppositions. Performative inconsistency derives from the self-referential denial of semantic or pragmatic presuppositions--in other words, a performatively self-falsifying proposition denies a necessary condition if its being meaningfully affirmed.27 The affirmation of a self-stultifying proposition, by contrast, denies one of its justificatory presuppositions.

除了'一个理论能在逻辑上自指不一致'外，一个理论能依据'自己被拒绝'或'内含其辩护性/语义性/语用性预设的反对'而得到不一致；换句话说，如果其被有意义地肯定，则是一个performatively self-falsifying的命题拒绝了一个必要条件。27 （作为对比，对self-stultifying命题的肯定，拒绝了部分其辩护性预设。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.
