Estimating a Bounded Normal Mean Under the LINEX Loss Function
Let X be a random variable from a normal distribution with unknown mean θ and known variance σ2. In many practical situations, θ is known in advance to lie in an interval, say [−m,m], for some m > 0. As the usual estimator of θ, i.e., X under the LINEX loss function is inadmissible, finding some competitors for X becomes worthwhile. The only study in the literature considered the problem of min...
متن کاملBounded Arithmetic, Cryptography and Complexity
This survey discusses theories of bounded arithmetic, growth rates of definable functions, natural proofs, interpolation theorems, connections to cryptography, and the difficulty of obtaining independence results.
متن کاملBounded Arithmetic and Descriptive Complexity
We study definability of languages in arithmetic and the free monoid by bounded versions of fixed-point and transitive-closure logics. In particular we give logical characterisations of complexity classes C by showing that a language belongs to C if and only if it is definable in either arithmetic or the free monoid by a formula of a certain logic. We investigate in which cases the bounds of fi...
متن کاملBounded discrete walks
This article tackles the enumeration and asymptotics of directed lattice paths (that are isomorphic to unidimensional paths) of bounded height (walks below one wall, or between two walls, for any finite set of jumps). Thus, for any lattice paths, we give the generating functions of bridges (“discrete” Brownian bridges) and reflected bridges (“discrete” reflected Brownian bridges) of a given hei...
متن کاملEquicontinuity and Almost Periodic Functions1
Let A be a separated uniform space, C(X, X) the set of continuous functions of X into X, and C(X) the set of real valued continuous functions on X provided with the topology of uniform convergence. For fEC(X) and aEC(X, X), fa will denote that element of C(X) such that (fa)(x) =f(xa)(xEX). Let fEC(X) and A EC(X, X). Then f is said to be almost periodic with respect to A if fA = [fa\ aEA ] is a ...
