Large Factorial Designs for Product Engineering and Marketing Research

Abstract. We propose an algorithm that incorporates both combinatorial and heuristic optimization methods for generating D-efficient factorial designs.This includes an approach that can automatically construct more than 115,000 orthogonal arrays, including at least one array for every known specification with fewer than 144 runs.

How a Factorial Design Works. Let's take a closer look at how a factorial design might work in a psychology experiment: The independent variable is the variable of interest that the experimenter will manipulate.; The dependent variable is the variable that the researcher then measures.; By doing this, psychologists can see if changing the …

Factorial Design

It has been argued that factorial designs epitomize the true beginning of modern behavioral research and have caused a significant paradigm shift in the way social scientists conceptualize their research questions and produce objective outcomes (Kerlinger & Lee, 2000).Factorial design can be categorized as an experimental methodology …

14.1

The simplest factorial design is the 2 × 2 factorial with two levels of factor A crossed with two levels of factor B to yield four treatment combinations. A special case of the 2 × 2 factorial with a placebo and an active formulation of factor A crossed with a placebo and an active formulation of factor B. This yields the four treatment regimens:

5.1: Factorial or Crossed Treatment Designs

A factorial design with (t) factors is identified using the (l_{1} l_{2} ldots l_{t}) notation, where (l_{i}) is the number of levels of factor (i) ((i=1,2, ldots,t)). For example, a factorial design with 2 factors A and B, where A has 4 levels and B has 3 levels, will have the (4 times 3) notation. ...

Factorial Design

This design structure is represented as a 2 × 2 (two by two) factorial design because there are two factors, and each factor has two levels. This four-celled structure is considered the simplest factorial design (Mee 2009). In a 2 × 2 factorial design, both factors have the ability to be manipulated or held as a constant.
