The compensation hypothesis predicts a positive causation from international economic openness to the size of the public sector, as governments step in to perform a risk mitigating role to counterbalance the increasing exposure to external risk and the economic dislocations caused by growing...

This paper presents optimum simple step-stress plans under the log-logistic cumulative exposure model. The likelihood function of the model parameters is derived, from which the Fisher information matrix and the asymptotic variance of the reliability estimate are obtained. Optimum times of...

The Birnbaum–Saunders distribution is useful for modeling reliability data. In this paper we obtain adjusted profile maximum likelihood estimators for the Birnbaum–Saunders distribution shape parameter under type II data censoring. We consider the adjustments to the profile likelihood...
