摘要:

We study a mixed linear model with two variance components. We suppose that one component is known. The objective of the paper is the estimation of the unknown component. The usual MINQE estimators seem to be unadapted to the problem. So we propose a new family of quadratic estimators, based on a natural class of estimators and the idea upon which the MINQE theory is built. All the estimators are compared on simulated data.

摘要:

Recently Gupta and Gupta [3] have discussed point estimation forR= Pr(a′x>b′y) wherexp× 1andyq× 1are two non-independent multivariate normal variates andaandbare two known vectors. We show how a lower confidence bound can be obtained forRand how this can be used to refine the inference for the application considered by Gupta and Gupta. Furthermore the case of independentxandyis considered and an application of this case is presented.

摘要:

sLingappaiah (1986) was the first to introduce the idea of Bayesian prediction in life testing when the size of the future sample is a random variable. In this paper we discuss the Bayesion prediction of the sample median when the parent distribution is a generalized Burr distribution (GBD), the old sample is censored type II and the size of the future sample is a random variable. A numerical illustration is provided.

摘要:

A non-parametric estimation method is proposed for the intensity of the Poisson process associated to a Boolean random function. The case studied is that of marks being half-spheres as primary functions, these half-spheres lying on a given horizontal plane. The proposed method is derived from the method presented in Györfi, Härdle, Sarda et Vieu [1989] for the case of time series. An application in soil science is presented.

摘要:

This paper deals with the two—sample (unequal sized) problem whereFm(x) andGn(x) are the two empirical distribution functions and investigates the null joint and marginal distributions of certain rank order statistics through the extended Dwass technique based on simple random walk with independent steps given by Aneja (1975).

摘要:

The paper is devoted to the development of the known splitting and Russian roulette method for Markov chains simulation. Representations for variances of unbiased parameter estimates and optimal numbers for branching are obtained. Efficiency of the method applied to M/M/1 queueing system is estimated.

摘要:

Considering a class of randomized response trials for eliciting sensitive information from a sample survey and a class of ordered sampling designs, a uniformly minimum variance unbiased estimator of population mean (of the sensitive character) has been obtained.
