查询词典 likelihood

It can be proven that, in the sense of NB, any system relying on linear inverse mapping to demodulate symbols cannot exceed Nyquist rate, unless it gives up orthogonality and adopts maximum-likelihood demodulation.

证明了采用逆映射解调的系统不可能在必要带宽意义下突破Nyquist速率。

For general point process model,we pose the mild condition under whichthe maximum likelihood estimateof the parameter possesses the strongconsistency and the convergence rate of iterated logarithm type.

首先对一般的点过程模型我们研究了随着观测时间的增加，参数极大似然估计的渐进性质。我们提出了相当广泛又便于验证的一组条件，足以保证极大似然估计具有强相合性及重对数型收敛速度。

De Jager and colleagues wrote in their analysis, was that because all study subjects received frequent nutrition counseling, the likelihood of vitamin deficiency may have been decreased in the study population, compared with that in the population at large.

de Jager博士及其同事在分析中写道，本研究的一个局限性是，由于所有的受试者均收到了频繁的营养忠告，故与一般人群相比，本研究的群体中维生素缺乏的可能性很可能有所下降。

In our childhood, due to certain degree of parity of treatment among sisters, brothers, if any, we may show kind of jealousness, resent or so, but when we gradually grow up, we can have better understanding toward this, since though it is not a recommended way to treat partially, it is natural for most of these parents, as friends above note, they are real people with colouful emotions, they may reveal more love/likelihood to the child they prefer, on aspects such as appearance, disposition, characteristics.

在我们孩提之时，由于在兄弟姐妹间受到的不同待遇，我们很自然的表现出妒忌，甚至憎恶。当我们长大之后，我们对此应有更好的理解。虽然来自父母的偏爱不是一种提倡的方式，但是我们也应看到，对于大多数父母来说，偏爱是最自然不过的人性流露，人都是有感情的，会对他们所喜欢的特质，如某个孩子的长相，气质，性格，表现出更多的爱意。

We will demonstrate the specification of reference prior distribution on the random covariance matrix. We will consider the approximate uniform shrinkage prior and approximate Jeffreys' prior. Both are formulated based on the approximated likelihood function. Under generalized linear mixed models, we show that the posterior mode under Jeffrey's prior is asymptotically closer to the REML estimate than the mode under uniform shrinkage prior does.

在广义线性混合模式下，我们证明了在样本数很大时，随机效应之变异数成份的后验众数和REML估计值会近似相等，同时也建立了后验众数和REML估计值的近似关系式，并提出了比较二种后验众数与REML估计值之间远近的准则。

Based on the pre-treated Chinese annual economic data from 1985 to 2004,the paper makes the time series stability test,the co-integration test(Johansen maximum likelihood method) and Grenger causal test,and makes a positive analysis of the long-term stable relation between the foreign direct investment in China and the growth of China's economy,which proves that the foreign di...

本文根据经过预处理的1985—2004中国有关年度经济数据，进行了时间序列平稳性检验、协整检验(Johansen极大似然方法)和格兰杰因果检验，实证分析了外商在中国直接投资与中国经济增长之间存在的长期稳定关系，证实了外商直接投资是我国经济增长的一个重要原因，并提出一些政策建议。

Still, the odds were against their encounter on this desolate island, and if Jackson had not appeared when he did, Nansen and Johansen in all likelihood would have died.

尽管如此，他们在这个荒凉的岛上相遇的几率仍然极低，而如果杰克逊没有出现在那里的话，南森和约翰森很有可能就会长眠于当地。

The main content of preparation before scoring is selection of characteristics, which mainly uses Logistic regression, contingency table analysis and artificial neural network. Personal credit scoring and evaluation mainly uses general discriminant analysis, refined decision tree model, improved genetic algorithm, probability neural network and behavioral scoring model. The effect test of personal credit scoring includes fitting effect test and fitness test. The former involves right prediction rate, Kappa consistency test, ROC curve, and the latter includes likelihood ratio test, Hosmer-Lemeshow test, etc.

评分前的准备工作主要是特征变量的筛选，其中使用的主要方法为Logisitic回归、列联表分析和人工神经网络；本文使用的个人信用评分与评估方法为广义判别分析、精练决策树模型、改进遗传算法、概率神经网络和行为评分模型；个人信用评估的效果检验包括拟合效果检验和拟合优度检验两个方面，前者涉及的方法有预测的正确率、Kappa一致性检验、ROC曲线，后者主要包括似然比检验、Hosmer-Lemeshow检验等。

Finally,the wind velocity data of Nantong observatory are used to verify the methods above-mentioned,and the likelihood ratio method and Kolmogorov statistic are used to test the fitness of the distribution.

引入涵盖Gumbel，Frechet，Weibull三类极值渐近分布的广义极值分布模型，给出该模型参数的极大似然估计的计算公式，并由此导出设计基本风速及其置信上限的计算方法。
