Fill Your Performance Modeling Toolbox with the Right Tools

Manufacturers of foods, drugs, consumer goods, and other products must make shelf-life determinations to give customers accurate product performance expectations. But there are numerous methods to quantify shelf life—including regression and non-linear degradation models. Confused? Learn to use the appropriate product stability and performance indicators for your specific products.

Statistician Steven Wachs outlines all your options—stability studies, data analysis, and modeling methods—in this detailed webinar. He will then take you step by step through designing a stability study and analyzing the results to estimate shelf life. He’ll illustrate his lesson with datasets and cover various approaches for factoring in additional variables that can affect a product’s shelf life.

After attending this instructive session, you will know how to carry out a stability study, determine performance specifications, and better define and determine shelf life. You will also understand different analysis approaches for aging, styles of regression modeling, and important facts about sample sizes.

Accurately determining your products’ shelf life is absolutely critical. Attend this virtual boot camp to get a thorough lesson on this task from one of the best in the business.
