Compound orthogonal arrays have recently been introduced as an alternative to Taguchi's direct product arrays for studying location and dispersion effects simultaneously. In this article, we provide a catalog of two-level compound orthogonal arrays for parameters of most practical interest. The arrays presented possess the maximum possible strength for

Column-orthogonal strong orthogonal arrays and sliced strong orthogonal arrays
Statistica Sinica, 2015A strong orthogonal array of strength t can achieve uniformity on finer grids when projected onto any g dimensions for any g less than t. It can be regarded as a kind of uniform space-filling design. Meanwhile, orthogonality is also desir- able for space-filling designs.

Nearly orthogonal arrays mappable into fully orthogonal arrays
Biometrika, 2014We develop a method for construction of arrays which are nearly orthogonal, in the sense that each column is orthogonal to a large proportion of the other columns, and which are convertible to fully orthogonal arrays via a mapping of the symbols in each column to a possibly smaller set of symbols.

Incomplete orthogonal arrays and idempotent orthogonal arrays
Graphs and Combinatorics, 1996The author introduces a notion of idempotency of orthogonal arrays (OA) of index unity, and the notion of incomplete OA. Denote by \(\text{OA}_\lambda(t,r,s)\) an array with \(r\) rows and \(\lambda s^t\) columns, with entries taken from an \(s\)-set \(E\), such that in each set of \(t\) rows every \(t\)-tuple of entries occurs precisely \(\lambda ...

On Covering Radius of Orthogonal Arrays
2020 Algebraic and Combinatorial Coding Theory (ACCT), 2020We obtain analytically upper bounds for the covering radius of orthogonal arrays (OAs) by investigations of the set of all feasible distance distributions of the corresponding OAs. We apply a procedure for reduction of the possible distance distributions of OA to improve the bound by 1 under certain assumptions.

Constructions of Nested Orthogonal Arrays
Journal of Combinatorial Designs, 2013AbstractA symmetric nested orthogonal array, denoted by NOA, is an OA which contains an OA as a subarray, where . Nested orthogonal arrays are useful in designing an experimental setup consisting of two experiments, the expensive one of higher accuracy being nested in a relatively less expensive one of lower accuracy.

On the construction of orthogonal arrays
2001Summary: The geometric representation of an orthogonal array is obtained using finite analytic projective geometry of the Galois field \(\text{GF}(s)\) of \(t\) dimensions, which can be denoted by \(\text{PG}(t, s)\), where \(s\) is a prime or a power of a prime number. We give relations between the parameters of orthogonal arrays and properties of the
