A generalization of the compound rayleigh distribution: using a bayesian method on cancer survival times

In this paper the generalized compound Rayleigh model, exhibiting flexible hazard rate, is high¬lighted. This makes it attractive for modelling survival times of patients showing characteristics of a random hazard rate. The Bayes estimators are derived for the parameters of this model and some survival time parameters from a right censored sample. This is done with respect to conjugate and discrete priors on the parameters of this model, under the squared error loss function, Varian's asymmetric linear-exponential (linex) loss function and a weighted linex loss function. The future survival time of a patient is estimated under these loss functions. A Monte Carlo simu¬lation procedure is used where closed form expressions of the estimators cannot be obtained. An example illustrates the proposed estimators for this model.     

Computation of the poisson-inverse gaussian distribution

Recursion relations suitable for rapid computation are derived for the probabilities of the compound Poisson distribution when the compounder is the inverse-Gaussian distribution. Series representation of the probabilities are given. Asymptotic results as well as approximations for probabilities, compared with the exact values, are investigated.     

Errors in inspection and grading distributional aspects ofscreening and merarchal screening

Continuing the studies of Johnson et al (1980) and Johnson and Kotz (1981), further distributions arising from models of errors in inspection and grading of samples from finite, possibly stratified lots are obtained. Screening, and hierarchal screening forms of inspection are also considered, and the effects of errors on the advantages of these techniques assessed.     

On Calculations Involving the Maximum Cell Frequency

We describe a method of computing the cumulative distribution function of the maximum and minimum cell frequencies in sampling distributions commonly encountered in the analysis of categorical data.The procedure is efficient for exact or approximate calculation in both homogeneous and non-homogeneous cases, is non-recursive, and does not require Dirichlet integrals.Some related statistical problems are also discussed.     

Cumulants of random sum distributions

Consider a random variable S being the sum of a number N of independent and identically distributed random variables X_j (j = 1, 2, ...) where the number N is itself a non-negative integer-valued random variable independent of the X_j An explicit expression of the r-th cumulant of S is given in terms of the cumulants of N and X_j, Asymptotic properties of the distribution of S are also discussed.     

试论我国再审改判标准的立法构想

近年来 ,理论界对再审程序的诸多问题进行了有益探索 ,但对其改判标准问题却鲜有论及。从理论上阐明我国再审改判标准并提出立法建议 ,对健全和完善我国再审程序具有重要价值     

广东电白沙院黎话记略

沙院黎话是广东茂名市电白县沙院镇流通的闽语。沙院黎话共17个声母,48个韵母,8个声调。其主要语音特点是：古心、生、书等声母均读边擦音 、文白读影响调类分化等。其主要语法特点是“俭”作男性名词后缀。用“糞pun^44”表示被动,用“贝poi^44”表示处置等。     

论悖论性语句与真值承担者

悖论性语句是具有悖论性质的语句,特点是从其真可以推出其为假,从其假可以推出其为真;陈述是陈述句所表达的内容,有一个陈述句就有一个陈述;命题是反映对象事实的思维形式,特点是要么真要么假。悖论性语句构成了陈述与命题的区别之所在。真值承担者的充分必要条件是,任一对象,如果是真值承担者,则它必须(i)′必须或者真或者假,不能既不真又不假;(ii)′必须或者不真或者不假,不能既真又假。悖论性语句不能符合真值承担者条件,因而陈述不能作为真值承担者;命题符合该条件,是真正的真值承担者。     

小句理论与汉语动词性论元补语小句分析

从对汉语“NP1 V NP2 XP”格式中V的考察着手,可初步认定汉语中语类选择一个论元补语小句的几类动词,并重新界定了汉语论元补语小句的标准;根据重新界定的论元补语小句的标准,确定了汉语中动词性小句的存在,使动结构中论元补语小句的存在;认为小句理论具有较强的解释力,它可以统一解释一些错综复杂的句子结构,是汉语研究中一种值得重视的句法和语义分析理论,体现了语法研究中理论上的经济性。     

蒙古语长句的结构特征及汉译转换型式

长句是蒙古语应用中常见的一种句式,依其结构特征分为限定型、联合型、引语型和混合型等类型。深入研究蒙语长句的结构特点及其在翻译转换中的一般规律,无疑对蒙汉双语教学和研究以及翻译实践活动具有重要意义。
