This year, I was fortunate enough to present at the JMP Discovery Summit Europe in Brussels, Belgium. When looking for something to bring back for my colleagues in Cary, I first thought of chocolate (actually, my first thought was probably beer, but that didn’t seem like a good idea). One
The first two posts in this series described the principles and methods of Quality by Design (QbD) in the pharmaceutical industry. The focus now shifts to the role of experimental design in QbD. Quality by Design in the pharmaceutical industry is a systematic approach to development of drug products and
The best time to plan an experiment is after you’ve done it – R.A. Fisher If you’ve read through my previous blog posts, I usually mention issues discovered during an experiment that I would change if I were to do the experiment again, or things to consider in the subsequent
Last time, I gave a Father’s Day tale of a father and son’s quest in dyeing toy cars. This time, I’ll share our results, but first remind you of the factors we studied: Car: A/B/C/D Dye type: Solid/liquid Dye amount: low/high (2 Tbsp liquid/4 Tbsp liquid per half cup, or
With Father’s Day fast approaching, it seemed fitting that I should share a story about a father and son bonding over design of experiments (DOE) and toy cars. Full disclosure: Some (including their wives) think both the father and son in this tale are too old to be playing with
In a previous blog post, I investigated my travel time to work using an estimate from Google Maps. In that post, my possible departure times to and from work were the same every day. However, it’s not uncommon in designs, even when using computer simulators, to have restrictions on the
In any computer software, it’s not unusual to have a set of preferences to allow customization to the settings. JMP is no exception. For example, in JMP 12, the Categorical platform allows for a great deal of the output to be tailored to the user’s preferences. Here’s what we see
Internet of Things (IoT) and design of experiments (DOE) are just two of the things you will hear about if you tune in to the Analytically Speaking webcast with Dennis J.K. Lin and Bradley Jones on June 10. Both are invited speakers at the 32nd Quality & Productivity Research Conference,
In my previous blog post, I created a 150-run space filling design to collect travel times over various departure times in the morning and evening. I wanted to see if I use this designed experiment to learn something useful about my commute. Google Maps gives a range of times for
Whenever I’m getting ready to go to or from work, I always have a notion that if I leave by a certain time, my drive will be smoother due to less traffic. Of course, even if I leave at the same time every day, my drive time is still going
