A Note on Probability Distributions with Increasing Generalized Failure Rates
X has an increasing generalized failure rate (IGFR) and is an IGFR distribution if g is weakly increasing for all such that < 1. Decreasing failure rate (DFR) or decreasing generalized failure rate (DGFR) distributions can be defined analogously. Clearly, if X is IFR it is also IGFR, but the reverse need not hold; many DFR distributions are IGFR. Pricing a service illustrates the use of IGFR di...
متن کاملA Note on Approximations to Discrete Probability Distributions
An iterative method is presented which gives an optimum approximation to the joint probability distribution of a set of binary variables given the joiat probability distributions of any subsets of the variables (any set of component distributions). The most significant feature of this approximation procedure is that there is no limitation to the number or type of component distributions that ca...
متن کاملNote on Probability Implication
In a recently published paper J. C. C. McKinsey has pointed out some difficulties which arise from Axiom I of my theory of probability implication. This axiom states the unambiguity of the degree p of a given probability implication (03VP) for the case that the class 0 is not empty, a condition formulated by (o), but postulates ambiguity of p in case of an empty class 0, this condition being fo...
متن کاملBounds on marginal probability distributions
We propose a novel bound on single-variable marginal probability distributions in factor graphs with discrete variables. The bound is obtained by propagating local bounds (convex sets of probability distributions) over a subtree of the factor graph, rooted in the variable of interest. By construction, the method not only bounds the exact marginal probability distribution of a variable, but also...
متن کاملA Note on Frame Distributions
In the context of constructive locale or frame theory (locale theory over a fixed base locale), we study some aspects of ’frame distributions’, meaning sup preserving maps from a frame to the base frame. We derive a relationship between results of Jibladze-Johnstone and Bunge-Funk, and also descriptions in distribution terms, as well as in double negation terms, of the ’interior of closure’ ope...
