While ignoring risks common in our day-to-day decision making, attempts to introduce the notion of into framework theory have run up against series well-known difficulties. In this paper, I will develop an enriched theoretic capable overcoming two major obstacles modelling risk. The key...

Unlike the real line, space, in dimension d ? 2, is not canonically ordered. As a consequence, extending to multivariate context fundamental univariate statistical tools such as quantiles, signs, and ranks anything but obvious. Tentative definitions have been proposed literature do enjoy basic properties (e.g., distribution-freeness of ranks, their independence with respect order statistic, sig...
