Screening Designs

Screening designs are among the most popular designs for industrial experimentation. They are typically used in the initial stages of experimentation. They examine many factors to identify those that have the greatest effect on the response or responses. The factors identified are then studied using more sensitive designs.

Screening designs generally require fewer experimental runs than other designs. They are attractive because they are a relatively inexpensive and efficient way to begin improving a process.

In a screening design, each continuous factor is usually set at two levels to economize on the number of ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
