Prophet inequalities for I.I.D. random variables with random arrival times
Suppose X1, X2, . . . are i.i.d. nonnegative random variables with finite expectation, and for each k, Xk is observed at the k-th arrival time Sk of a Poisson process with unit rate which is independent of the sequence {Xk}. For t > 0, comparisons are made between the expected maximum M(t) := E[maxk≥1 Xk I(Sk ≤ t)] and the optimal stopping value V (t) := supτ∈T E[Xτ I(Sτ ≤ t)], where T is the s...
متن کاملSOME PROBABILISTIC INEQUALITIES FOR FUZZY RANDOM VARIABLES
In this paper, the concepts of positive dependence and linearlypositive quadrant dependence are introduced for fuzzy random variables. Also,an inequality is obtained for partial sums of linearly positive quadrant depen-dent fuzzy random variables. Moreover, a weak law of large numbers is estab-lished for linearly positive quadrant dependent fuzzy random variables. Weextend some well known inequ...
متن کاملMaximal Inequalities for Associated Random Variables
In a celebrated work by Shao [13] several inequalities for negatively associated random variables were proved. In this paper we obtain some maximal inequalities for associated random variables. Also we establish a maximal inequality for demimartingales which generalizes and improves the result of Christofides [4].
متن کاملProphet Inequalities for Averages of Independent Non-Negative Random Variables
The main purpose of this paper is to prove the following theorem, which sharpens results of Krengel and Sucheston [11, 12] in which the weaker constant 2(1 +-(3) was obtained. (Here EX is the expected value of the ran dom variable X, and ~ and T are the sets of stop rules ~ n, and of a.s. finite stop rules, respectively.) Theorem 1.1. If Xl' ... , X n are independent non-negative random variab...
