A note on a comparison of confidence interval techniques in truncated life tests

Naval Research Logistics Quarterly, 1971
AbstractSeveral approximate procedures are available in the literature for obtaining confidence intervals for the parameter A of an exponential distribution based on time truncated samples. This paper contains the results of an empirical study comparing three of these procedures.

Sequential Sampling Plan in the Truncated Life Test for Weibull Distribution

Journal of Testing and Evaluation, 2018
Abstract The truncated life test is usually applied for reducing experiment time. The lifetime of a product is assumed as its quality characteristic, and the sequential sampling (SS) plan is applied in the context of the truncated life test. In SS, the samples are selected from the lot stage by stage.

A New Extended Exponentiated Exponential Distribution with Application to Truncated Life Tests

Journal of Statistical Modelling and Analytics, 2023
In this paper, the Extended Exponentiated Exponential distribution was developed from the New Extended Exponentiated-G family of distributions. Some mathematical properties of the newly derived distribution such as moment, moment generating function, quantile function, hazard function, survival function, odd function, distribution of order statistic ...

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 plans based on truncated life tests for weighted exponential distribution

Communications in Statistics - Simulation and Computation, 2015
ABSTRACTGupta and Kundu proposed a new class of weighted exponential distributions using the idea of Azzalini. In this article, we develop an acceptance sampling plan for the weighted exponential distribution under a truncated life test. For various acceptance numbers, consumer’s confidence levels and values of the ratio of the experimental time to the

Acceptance Sampling from Truncated Life Tests

2019
Acceptance sampling approach is helpful in reducing the cost and time of the inspection of a submitted product. In this modern era, the reliability of the products is very high. The experimenters may wait a long time to record the required numbers of failures.

Modified Sequential Probability Ratio Test Based on Truncated Life Tests on the Exponential Distribution Functions

Journal of Physical Mathematics & its Applications, 2023
Modified Sequential probability ratio test (MSPRT) technique helps to increase the reliability and speed of stabilization detection on the Non homogenous poison process (NHPP) with the maximum number of software faults to reduce error between the consumer risk and producer risk, with the time cumulative system of hours.

Acceptance sampling plans based on truncated life tests for Rama distribution

International Journal of Quality & 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

Attribute control charts for the Dagum distribution under truncated life tests

Life Cycle Reliability and Safety Engineering, 2019
In this paper, an attribute control chart for lifetime of the product follows Dagum distribution under number of failures before a specified time period is proposed. The sensitivity of the proposed chart is studied using the average run length (ARL).

A control chart for the generalized exponential distribution under time truncated life test

Life Cycle Reliability and Safety Engineering, 2020
The usual assumption in the application of control chart is that the process follows a normal distribution. However, in practice, the underlying process distribution is either unknown or non-normal and the use of control chart assuming normality often leads to false alarm in the process.
