9.1 Assume that an experimentalist has a list of seven possible factors and is about to run a screening design to identify the most vital ones for further experimentation.

Write a code in some software to generate data from the model

where ???? = 0.1. Make use of

(a) A two-level saturated experimental design, that is a 2⁷⁻⁴ design as in Table 9.1.

(b) A Plackett–Burman L₁₂ design (Table 9.2) with four empty columns.

Reflect on the differences in the conclusions.
