Abstract : the sample breakdown point of a test is defined as the smallest proportion of arbitrary outlier in the sample that reverses the test decision . in this paper , wegive the sample breakdown point of a test for maximum likelihood estimate of exponential distribution parameter and analyze the asymptotically normal characteristic of the sample breakdown point
文摘:如何量化一种统计方法对异常值的不敏感性一直是稳健统计研究的一个重要课题.检验的样本崩溃点是样本中能逆转判决的离群值的最小比例.在研究相关文献的基础上，计算出指数分布参数极大似然估计检验的样本崩溃点，并分析了样本崩溃点的渐近正态性，为量化统计方法的稳健性提供了一种新的途径
The paper explored the pdf of the spatial distribution of the day precipitation . the result shows that the weibull distribution is good on describing the heterogeneous of the spatial distribution of the day precipitation in china . the exponential distribution is n ' t ideally suited to the day precipitation
利用负指数分布和weibull分布拟合全国范围内的逐日降水水平空间概率分布模式，发现负指数分布模式并不能很好的拟合大范围区域逐日降水量场空间分布型，而weibull分布的拟合效果很好，表明用weibull分布描述中国区域逐日降水量空间分布非均匀性的分布律是非常适宜的。
At first , by using the feature that the excess delays of nlos propagation follow the exponential distribution , the los propagation parameters are reconstructed and the toa parameters measured from all bs are preprocessed . then , the ms ' s position is estimated by the los locating algorithm with the preprocessed data . finally , to mitigate the effect of the errors in reconstructed parameters , the estimated results are smoothed
首先，利用非视距传播时延服从指数分布的特点，对不同基站一次测量的数据进行预处理，重构视距传输参量；然后，对处理后的数据采用视距定位算法估计移动台位置；最后，对估计结果进行平滑后处理，以减小重构出的参量误差的影响，进一步提高定位精度。
First of all , least square method and modified maximum likelihood estimation of zero - failure data for the exponential distribution , the weibull distribution , the normal distribution and the logarithm normal distribution are given , among them , the bayes method in the estimation to the failure probability is introduced
首先,分别采用最小二乘法和修正极大似然估计法对指数分布、 weibull分布、正态及对数正态分布的无失效数据处理进行了研究,其中,在对失效概率的估计中引入了bayes方法。
In this thesis , the critical components of pcs are analyzed and tested in detail . i present the scheme of reliability qualification test of capacitors , furthermore , analyze the sampling inspection scheme theoretically for capacitors and put forward the proposals to improve this scheme . for most of components in pcs with high reliability or long lifecycle , which need great investment of time and material for their reliability tests , this paper provides a new and effective statistical method for this kind of components - the progressive stress accelerated life testing with exponential distribution
可靠性试验也是可靠性工程的重要组成部分，能源系统许多元器件为高可靠性、长寿命器件，且大部分是非标准器件，为保证整个系统的可靠性，必须对备选元器件进行可靠性试验，本文对能源系统关键器件进行了详细的试验分析，给出了电容器的鉴定试验方案，对其抽样试验方案进行了理论分析并给出了方案改进建议。
