In this article, I present a simple classification scheme for epidemiological study designs, a topic about which there has been considerable debate over several decades. I will argue that when the individual is the unit of analysis and the disease outcome under study is dichotomous, then epidemiological study designs can best be classified according to two criteria: (i) the type of outcome unde...

We present a mechanism for computing asymptotically stable school optimal matchings, while guaranteeing that it is an asymptotic dominant strategy for every student to report their true preferences to the mechanism. Our main tool in this endeavor is differential privacy: we give an algorithm that coordinates a stable matching using differentially private signals, which lead to our truthfulness ...

Bivariate lifetime distributions are of great importance in studies related to interdependent components, especially engineering applications. In this paper, we introduce two bivariate assuming three- parameter Weibull marginal distributions. Some characteristics the proposed as joint survival function, hazard rate cross factorial moment and stress-strength also derived. The inferences for para...

10 Most contemporary philosophical discussions of utility either follow the 11 utility representations of von Neumann and Morgenstern that use prob12 ability and the expectation principle to measure individual utilities in a 13 way that leaves zero point and unit undetermined, or assume that psy14 chology can ultimately deliver utility measurement on an absolute scale. 15 From the second point ...

In this paper we say that a preference for freedom of choice is justifiable if there exists a reflexive and complete binary relation on the set of alternatives, such that one opportunity set is at least as good as a second, if and only if the there is at least one alternative from the first set which is no worse than any alternative of the two sets combined together, with respect to the binary ...

Let P be an orthogonal polygon. Consider a sliding camera that travels back and forth along an orthogonal line segment s ⊆ P as its trajectory. The camera can see a point p ∈ P if there exists a point q ∈ s such that pq is a line segment normal to s that is completely contained in P . In the minimum-cardinality sliding cameras problem, the objective is to find a set S of sliding cameras of mini...
