摘要

In this work we will be life-test a new industrial product. We will be assuming an underlying three-parameter Inverse Weibull distribution and a linear acceleration condition. To estimate the three parameters of the Inverse Weibull model we will use a maximum likelihood approach for censored failure data. To evaluate the accuracy (significance) of the parameter values obtained under normal conditions for the underlying three-parameter Inverse Weibull model we will apply to the expected normal failure times a sequential life test using a truncation mechanism. An example will illustrate the application of the proposed approach.
