WebIn this paper, we consider the problem of estimating stress-strength reliability for inverse Weibull lifetime models having the same shape parameters but different scale parameters. We obtain the maximum likelihood estimator and its asymptotic distribution. Since the classical estimator doesn’t hold explicit forms, we propose an approximate maximum … WebFurthermore, if we solve the Weibull reliability equation for η we have: If we substitute the above equation into Eqn. (3) and take the natural logarithm on both sides then: From the previous equation we can see that: If then . If then . As a result, we can conclude that: If then as β increases the required test time (t test) will also increase. boat dock wiring boat dock walls
