Estimation of a Time-Truncated Exponential Parameter Used in Life Testing

Journal of the American Statistical Association, 1977
Abstract This article proves the asymptotic unbiasedness and consistency when the sample size of the maximum likelihood estimate of the mean θ of an exponential distribution in a time-truncated experiment is random. Convergence of to with μ and σ2 independent of x is established.

Acceptance sampling based on truncated life tests for generalized Rayleigh distribution

Journal of Applied Statistics, 2006
This paper considers the problem of an acceptance sampling plan for a truncated life test when the lifetime follows the generalized Rayleigh distribution. For different acceptance numbers, confidence levels, and values of the ratio of the fixed experiment time to the specified mean life, the minimum sample sizes necessary to ensure the specified mean ...

Acceptance sampling plan based on truncated life tests for exponentiated fréchet distribution

Journal of Statistics and Management Systems, 2013
Abstract In this paper, exponentiated Frechet distribution is considered as a model for a life time random variable when the life test is truncated at a pre-assigned time. The operating characteristic functions values of the suggested sampling plans and the corresponding producer's risk are obtained.

A group acceptance sampling plan for truncated life test having Weibull distribution

Journal of Applied Statistics, 2009
In this paper, a group acceptance sampling plan for a truncated life test is proposed when a multiple number of items as a group can be tested simultaneously in a tester, assuming that the lifetime of a product follows the Weibull distribution with a known shape parameter.

Acceptance sampling plans based on truncated life tests for Rama distribution

International Journal of Quality and Reliability Management, 2019
PurposeLifetime data are used in many different applied sciences, like biomedicine, engineering, insurance and finance and others. The purpose of this paper is to develop a new acceptance sampling plans for Rama distribution when the mean lifetime test is truncated at a pre-determined time. The minimum sample sizes required to assert the specified life

Acceptance Sampling Based on Truncated Life Tests in the Birnbaum Saunders Model

Risk Analysis, 2004
We develop acceptance sampling plans assuming that the life test is truncated at a preassigned time. The lifetimes of the test units are assumed to follow the Birnbaum Saunders distribution. The minimum sample size necessary to ensure the specified average life is obtained and the operating characteristic values of the sampling plans and producer's ...

Truncated Sequential Life Tests for a 3-Way Decision Procedure

IEEE Transactions on Reliability, 1973
Eleven sets of test plans are given for testing ``? = ?0'' against the alternative ``? = ?1 ?0'' where ? is the failure rate. The results are useful for incentive plans and life-cycle costing applications, and are fundamental in the life testing of equipment, whether a consumer or industrial item, during the constant failure-rate period.
