GSK's Peterson Has Just What Your Design Space Needs

In case you missed it, we recently posted an article on multivariate predictive distribution by GlaxoSmithKline's John Peterson, director of the research statistics unit in the company's drug development sciences department. (The article will also appear in the Nov/Dec issue of Pharmaceutical Manufacturing magazine.) When we first approached Peterson--a highly accomplished statistician, among other things--about writing an article, it was with an eye towards explaining Quality by Design and the concept of a design space from a statistical viewpoint, but for readers who are non-statisticians. Peterson willingly assented and, if you read the article, I hope you agree that he has not only done as planned, but has also put forth some pretty heady concepts that statisticians involved in drug industry Quality by Design projects will benefit from tremendously.

The article seeks to encourage us to, as he says, "understand randomness and think stochastically." It's a testament to the power of statistics to help manufacturers understand and control their processes, in the name of making drug development smarter.

Great appreciation to Dr. Peterson for sharing his vision for us. I hope that you get as much from the article as I, a non-statistician, have, and we'd love to hear your comments.
