The Statistical Analysis of Two-Parameter Exponential Distribution with Full Sample Size Based on Tampered Failure Rate Model under Step-Stress Accelerated Life Testing

WU Sheng-rong

Abstract

We obtain the maximum likelihood estimator and the simulated moment estimator of parameters of two-parameter exponential distribution with full sample size based on tampered failure rate model under step-stress accelerated life testing.Thereafter we show the feasibility of this method by Monte-Carlo simulation.
