| Taguchi
developed a series of arrays, often referred
to as Taguchi Orthogonal
Arrays, for use with Taguchi
Designs. These are designated
Ln arrays, where 'n' is the number
of treatments.
The columns in these arrays are highly
confounded. They are generally used as screening
designs, with only selected
interactions investigated. The arrays include
two, three, four, and mixed level designs.
Taguchi developed a system of
Linear Graphs to help allocate
factors
to the columns in the arrays.
