Installation

pip install definitive_screening_design

Example

Generate a Definitive Design screening with three numerical and two 2-levels categoricals factors, using the protocol presented in the 2013 paper. The result is a Pandas DataFrame.

import definitive_screening_design as dsd
dsd.generate(n_num=3, n_cat=2)
