On Orthogonal Arrays

open access: yesThe Annals of Mathematical Statistics, 1966
It was shown in [11] that one can construct orthogonal arrays $(\lambda 2^3, k + 1, 2, 3)$ from arrays $(\lambda 2^2, k, 2, 2)$ with the maximum number of constraints $k + 1$ provided that $k$ is the maximum number of constraints for the arrays of strength two. This result is generalized here to construction of arrays $(\lambda 2^{t + 1}, k + 1, 2, t +

Use of orthogonal arrays and design of experiment via Taguchi L9 method in probability of default [PDF]

open access: yesAccounting, 2018
The Taguchi’s orthogonal array is based on a mathematical model of factorial designs. This paper investigates the effects of four parameters in Probability of Default (PD) using Black-Scholes model (BSM) for call option at one period by considering asset

Matroidal Entropy Functions: A Quartet of Theories of Information, Matroid, Design, and Coding

open access: yesEntropy, 2021
In this paper, we study the entropy functions on extreme rays of the polymatroidal region which contain a matroid, i.e., matroidal entropy functions. We introduce variable strength orthogonal arrays indexed by a connected matroid M and positive integer v
