A generalized cubic splining algorithm enables us to evaluate recursively-defined convolution integrals for a wide variety of distribution functions. This algorithm has been used to evaluate the renewal function, the variance function, and the integr

A general expression is obtained for the reliability of two dependent paralleled devices, where the form of the dependency involves a change in the operating conditions or environment (and, accordingly, the life distribution) of the survivor when one

Two types of warranties are analyzed. These are the free-replacement warranty, under which failed items are replaced free of charge until a specified total operating time has been achieved, and the pro rata warranty, under which items that fail prior

Under a free-replacement warranty of duration W, the customer is provided, for an initial cost of C, as many replacement items as needed to provide service for a period W. Payments of C are not made at fixed intervals of length W, but in random cycle

On obtient la matrice de covariance asymptotique des estimateurs de moment et on fournit des listings pour des programmes informatiques BASIC qui engendrent des tables utiles pour calculer les estimations et pour estimer la matrice de covariance asym

Let X 1 and X 2 be normally distributed random variables with zero means, variances σ11 and σ22, respectively and covariance σ12. Let Then the moments about the origin μ′ n of the radial error where F(a, b; c; z) is the hypergeometric function.

This study examines and develops new techniques for analyzing life test data. It obtains estimates for the life distribution in the use environment on based data from both the use and the accelerated environments. The techniques require only physical

The simulation of a process may require the use of sampling techniques involving the generation of random vectors from a multivariate normal population with a specified variance-covariance matrix. This is an expository paper which discusses two metho

Thii study deals with the “burn-in” process. In this process, items whose failure rate is assumed to decrease with time are put on test (burnt-in) until a fixed amount of time has elapsed (truncated sampling) or until a fixed number of failures h

The problem of estimating reliability of a system undergoing development testing is examined. It is assumed that the test program is conducted in K stages and that similar items are tested within each stage. In addition, it is assumed that the probab
