“…We denote this generic size as n * and the quotient basis is said to be generic. Indeed, it was previously observed that a generic set of quotient basis exists at certain increments of n where the least aberration is observed [6]. If n is not generic, the quotient basis can be used to identify the polynomial accuracy of the algebraic quadrature but the confounding or aberration effects may have stronger influence on the accuracy of the algebraic quadrature.…”

“…The main purpose of the paper is to introduce a new theory of quadrature based on the socalled algebraic method in experimental design. This method was introduced originally to study interpolation and aliasing in factorial design [6], but has the advantage of delivering a possible interpolator for any data over any experimental design with an a priori determination of the design's polynomial exactness. We refer to a set of quadrature points as a design to maintain the connection.…”

Abstract. A general method of quadrature for uncertainty quantification (UQ) is introduced based on the algebraic method in experimental design. This is a method based on the theory of zero dimensional algebraic varieties. It allows quadrature of polynomials or polynomial approximands for quite general sets of quadrature points, here called 'designs'. The method goes some way to explaining when quadrature weights are non-negative and gives exact quadrature for monomials in the quotient ring defined by the algebraic method. The relationship to the classical methods based on zeros of orthogonal polynomials is discussed and numerical comparisons made with methods such as Gaussian quadrature and Smolyak grids. Application to UQ is examined in the context of polynomial chaos expansion and probabilistic collocation method where solution statistics are estimated.

“…A study for the class of Latin hypercube designs carried out in Bernstein et al [2010] shows different situations that can occur when computing the algebraic fan. Moreover by Theorem 30 in Pistone et al [2001] for a design whose points are chosen at random (with respect to any Lebesgue absolute continuous measure) the algebraic fan equals the statistical fan with probability one.…”
