Bivariate Stochastic Ageing Classes

The book BIVARIATE STOCHASTIC AGEING CLASSES introduce several bivariate life time distributions for stochastic systems which may fail during the operating stage of their life-times. The dual versions of these ageing classes are given. The characteristics, closure, preservation and transformation properties are presented. Moment inequalities for some of the bivariate stochastic ageing classes have been deduced. A conjecture on a specific ageing class is given.
