متن کاملGeneral Saddlepoint Approximations of Marginal Densities and Tail Probabilities
Saddlepoint approximations of marginal densities and tail probabilities of general nonlinear statistics are derived. They are based on the expansion of the statistic up to the second order. Their accuracy is shown in a variety of examples, including logit and probit models and rank estimators for regression.
متن کاملOn Sharp Bounds for Marginal Densities of Product Measures
We discuss optimal constants in a recent result of Rudelson and Vershynin on marginal densities. We show that if f is a probability density on R of the form f(x) = ∏n i=1 fi(xi), where each fi is a density on R, say bounded by one, then the density of any marginal πE(f) is bounded by 2 , where k is the dimension of E. The proof relies on an adaptation of Ball’s approach to cube slicing, carried...

متن کاملSIC-POVMs and Compatibility among Quantum States
An unexpected connection exists between compatibility criteria for quantum states and Symmetric Informationally Complete quantum measurements (SIC-POVMs). Beginning with Caves, Fuchs and Schack’s "Conditions for compatibility of quantum state assignments", I show that a qutrit SIC-POVM studied in other contexts enjoys additional interesting properties. Compatibility criteria provide a new way t...
