Constant stress accelerated life test model and its application-Weibull distribution

The accelerated life test is a basic reliability test methods, which tests the data of accelerated life test whether obeying the Weibull distribution, and then come to the acceleration factor and accelerated life equation. With different stress levels in the test data, using Weibull distribution model, which parameters are estimated point estimates and interval estimation works out the estimation for charaeteristic quantity of reliability under the normal stress conditions.
