Exponentiated Weibull Model For Analyzing Bathtub Failure – Rate Data

S. Shunmugapriya, S. Lakshmi

Abstract


A simple generalization of the Weibull distribution offered here is well suited for modeling bathtub failure rate life time data and for testing goodness-of-fit of the Weibull and negative exponential models as sub hypothesis. For example the theoretical study for the effect of stress on ACTH levels with the mesocortical dopamine (DA) system including of the HPA axis regulation which were handled (H) or Non-handled (NH) postnatally. The result shows that the concentration of ACTH levels is connected with hazard failure rate.
