Best Simultaneous Monotone Approximants in Orlicz Spaces
(Taylor & Francis, 2013-01)
Let f = (f1, , fm ), where fj belongs to the Orlicz space [0, 1], and let w = (w1, , wm ) be an m-tuple of m positive weights. If ⊂ [0, 1] is the class of nondecreasing functions, we denote by ,w(f, ) the set of best ...
A Closed-Form Approximation for the CDF of the Sum of Independent Random Variables
(Institute of Electrical and Electronics Engineers, 2017-01)
In this letter, we use the Berry-Esseen theorem and the method of tilted distributions to derive a simple tight closed-form approximation for the tail probabilities of a sum of independent but not necessarily identically ...
Approximations for Densities of Sufficient Estimators
(Springer, 2010)
Durbin (1980a) proposed a simple method for obtaining asymptotic expansions for the densities of sufficient estimators. The expansion is a series which is effectively in powers of n-1, where n is the sample size, as compare ...
A more general theory of static approximations for conjunctive queries
(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2018)
Conjunctive query (CQ) evaluation is NP-complete, but becomes tractable for fragments of bounded hypertreewidth. Approximating a hard CQ by a query from such a fragment can thus allow for an efficient approximate evaluation. ...
Existence and characterization of best φ-approximations by linear subspaces
(Walter de Gruyter GmbH, 2017-07)
Given an Orlicz space Lφ, we give very relaxed sufficient conditions on φ to ensure that there exists a best φ-approximation from any finite dimensional bounded linear subspace S ⊂ Lφ. In addition, given an operator T, ...
Approximate recursive equilibrium with minimal state space
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2013-02-26)
This paper shows existence of approximate recursive equilibrium with minimal state space in an environment of incomplete markets. We prove that the approximate recursive equilibrium implements an approximate sequential ...
Weighted Best Local ||.|| - Approximation in Orlicz Spaces
(Universidad de Jaén, 2010-06-21)
In this paper we prove the existence of best multipoint local ||·||−approximation to a function f from an N−dimensional space SN for a suitable integer N. This problem is considered in an arbitrary Orlicz space for both ...
Efficient approximations of conjunctive queries
(Society for Industrial and Applied Mathematics, 2014)
When finding exact answers to a query over a large database is infeasible, it is natural
to approximate the query by a more efficient one that comes from a class with good bounds on the
complexity of query evaluation. ...
Two Families Of H(div) Mixed Finite Elements On Quadrilaterals Of Minimal Dimension
(SIAM PublicationsPhiladelphia, 2016)
Convergence of the approximate cores to the aspiration core in partitioning games
(Springer, 2015-07)
The approximate core and the aspiration core are two non-empty solutions for cooperative games that have emerged in order to give an answer to cooperative games with an empty core. Although the approximate core and the ...
