The generalized half-normal (GHN) distribution and progressive type-II censoring are considered in this article for studying some statistical inferences of constant-stress accelerated life testing. The EM algorithm is considered to calculate the maximum likelihood estimates. Fisher information matrix is formed depending on the missing information law and it is utilized for structuring the asymptomatic confidence intervals. Further, interval estimation is discussed through bootstrap intervals. The Tierney and Kadane method, importance sampling procedure and Metropolis-Hastings algorithm are utilized to compute Bayesian estimates. Furthermore, predictive estimates for censored data and the related prediction intervals are obtained. We consider three optimality criteria to find out the optimal stress level. A real data set is used to illustrate the importance of GHN distribution as an alternative lifetime model for well-known distributions. Finally, a simulation study is provided with discussion. 相似文献

德国行政赔偿制度有着不同于大陆法系国家和普通法系国家行政赔偿制度的特色,这种特色突出体现在行政赔偿基础的赔偿请求权和对行政赔偿案件进行救济的赔偿审理制度两个方面。德国行政赔偿制度的特色是由在漫长的历史过程中所形成的思想因素、制度因素和文化因素造就而成。 相似文献

Abstract. Recurrent event data are largely characterized by the rate function but smoothing techniques for estimating the rate function have never been rigorously developed or studied in statistical literature. This paper considers the moment and least squares methods for estimating the rate function from recurrent event data. With an independent censoring assumption on the recurrent event process, we study statistical properties of the proposed estimators and propose bootstrap procedures for the bandwidth selection and for the approximation of confidence intervals in the estimation of the occurrence rate function. It is identified that the moment method without resmoothing via a smaller bandwidth will produce a curve with nicks occurring at the censoring times, whereas there is no such problem with the least squares method. Furthermore, the asymptotic variance of the least squares estimator is shown to be smaller under regularity conditions. However, in the implementation of the bootstrap procedures, the moment method is computationally more efficient than the least squares method because the former approach uses condensed bootstrap data. The performance of the proposed procedures is studied through Monte Carlo simulations and an epidemiological example on intravenous drug users. 相似文献

Computing maximum likelihood estimates from type II doubly censored exponential data 总被引:1,自引:0,他引:1

It is well-known that, under Type II double censoring, the maximum likelihood (ML) estimators of the location and scale parameters, θ and δ, of a twoparameter exponential distribution are linear functions
of the order statistics. In contrast, when θ is known, theML estimator of δ does not admit a closed form expression. It is shown, however, that theML estimator of the scale parameter exists and is unique. Moreover, it has good large-sample properties. In addition, sharp
lower and upper bounds for this estimator are provided, which can serve as starting points for iterative interpolation methods
such as regula falsi. Explicit expressions for the expected Fisher information and Cramér-Rao lower bound are also derived.
In the Bayesian context, assuming an inverted gamma prior on δ, the uniqueness, boundedness and asymptotics of the highest
posterior density estimator of δ can be deduced in a similar way. Finally, an illustrative example is included. 相似文献

Oiler, Gomez & Calle (2004) give a constant sum condition for processes that generate interval‐censored lifetime data. They show that in models satisfying this condition, it is possible to estimate non‐parametrically the lifetime distribution based on a well‐known simplified likelihood. The author shows that this constant‐sum condition is equivalent to the existence of an observation process that is independent of lifetimes and which gives the same probability distribution for the observed data as the underlying true process. 相似文献

我国现行刑事诉讼法在保障犯罪嫌疑人人权方面迈进了一大步,但是司法实践中仍然存在着侵犯犯罪嫌疑人人权现象。鉴于此,只有转变刑诉观念、继续完善立法、提高公安司法人员素质,才能根除这种现象,才能充分保障犯罪嫌疑人的人权。 相似文献

网络人肉搜索与侵犯个人隐私权问题研究 总被引:5,自引:0,他引:5
通过对一些有关于人肉搜索的典型案例分析的基础上,揭示了人肉搜索的运行机制。人肉搜索是一种特殊的信息搜索方式,同时也是一种新的信息生产方式。正确使用的话可以弥补机器搜索引擎的不足,但如果被滥用的话,则可能造成对个人隐私权的侵犯。 相似文献

1996年的刑事诉讼法确认了律师在侦查阶段介入诉讼,会见犯罪嫌疑人的权利,但这一规定并未使律师在侦查阶段会见犯罪嫌疑人成为常态,解决侦查阶段的会见难,应该另辟蹊径,从以下方面入手:确立沉默权制度;规定在阻止律师会见的情况下所获得的口供不能作为定案的根据;赋予法院对侦查活动的程序合法性进行审查的权力。 相似文献
