In SCCDdesign: Construction of Screening Designs for Mixed Level Continuous and Categorical Factors

Constructs an orthogonal design for an odd-level factor and an even-level factor using a conference matrix and a Hadamard matrix, respectively.

Description

Constructs an orthogonal design for an odd-level factor and an even-level factor using a conference matrix and a Hadamard matrix, respectively.

Usage

odd_even_design(a, b, m)

Arguments

a	Number of levels for the odd-level factor.
b	Number of levels for the even-level factor.
m	Order of the conference and Hadamard matrices. Must be a multiple of 4.The design containsm factors of the odd-level type and m - 1 factors of the even-level type.

Value

A matrix containing the constructed design. The first m columns correspond to the odd-level factors and are constructed using a conference matrix, while the remaining m - 1 columns correspond to the even-level factors and are constructed using a Hadamard matrix with its first column removed.
