Aging Intensities Vector for Bivariate Absolutely Continuous Distributions
Next, we propose to use the bivariate aging intensities vector to characterize bivariate absolutely continuous distributions (Sect. 4.1). Such distributions, e.g., bivariate Weibull (Sect. 4.2), we often use to describe the lifetime of two components system. Further, a bivariate aging intensity order is studied (Sect. 4.3). To show the practical usefulness of the aging intensities vector, the analysis of this vector through the real data is performed (Sect. 4.4).
