pbDesign: Plackett-Burman Designs
In qualityTools: Statistical Methods for Quality Science

Description Usage Arguments Value Note Author(s) References See Also Examples

Creates a Plackett-Burman design.

1	pbDesign(n, k, randomize = TRUE, replicates = 1)

`n`	integer value giving the number of trials.
`k`	integer value giving the number of factors.
`randomize`	logical value (‘TRUE’/‘FALSE’) - randomizes the RunOrder of the design. By default `randomize` is set to ‘TRUE’.
`replicates`	Integer giving the number of replicates.

pbDesign returns an object of class pbDesign.

This function creates Placket-Burman Designs up to n=48. Bigger Designs are not implemented because of lack in practicability. For the creation either the number of factors or the number of trials can be denoted. Wrong combinations will lead to an error message. Originally Placket-Burman-Design are applicable for number of trials divisible by 4. If n is not divisble by 4 this function will take the next larger Placket-Burman Design and truncate the last rows and columns.
