http://causality.cs.ucla.edu/blog/index.php/2024/11/05/frechet-inequalities/ WebThe Fréchet bounds of a set of bivariate distributions with fixed marginals are characterized by the monotonicity of their supports. Also they are characterized by their totally positive dependence of order 2 (TP2) and reverse regular of order 2 (RR2) properties. A corollary of these results is the existence of a measurable transformation ...

WebApr 23, 2010 · This paper reviews and partially elaborate on several developments of improved Hoeffding–Frechet bounds which assume some restriction on the dependence structure additional to the information on the marginals and describes applications of the results to obtain improved VaR bounds for the joint portfolio of risk vectors. 7 It is evident that structurally the above inequalities are analogues of the classical Fréchet bounds for the logical conjunction. It is also worth to notice that when the matrices ρ A , ρ B {\displaystyle \rho ^{A},\rho ^{B}} and ρ A B {\displaystyle \rho ^{AB}} are restricted to be diagonal, we obtain the classical … See more In probabilistic logic, the Fréchet inequalities, also known as the Boole–Fréchet inequalities, are rules implicit in the work of George Boole and explicitly derived by Maurice Fréchet that govern the … See more The proofs are elementary. Recall that P(A ∨ B) = P(A) + P(B) − P(A & B), which implies P(A) + P(B) − P(A ∨ B) = P(A & B). Because all … See more Similar bounds hold also in quantum mechanics in the case of separable quantum systems and that entangled states violate these bounds. Consider a composite quantum system. In particular, we focus on a composite quantum system AB made by two … See more If the probability of an event A is P(A) = a = 0.7, and the probability of the event B is P(B) = b = 0.8, then the probability of the conjunction, i.e., the joint event A & B, is surely in the interval These intervals are contrasted with the results obtained … See more When the input probabilities are themselves interval ranges, the Fréchet formulas still work as a probability bounds analysis.
