Stability Studies and Estimating Shelf Life with Regression Models

Live Webinar

  • 90 minutes

Manufacturers of foods, drugs, consumer goods, and other products must determine the shelf life of their products so that customers know when the product can be expected to perform as intended. Many approaches are available to quantify the "shelf life" and the method(s) chosen often depends on the testing time available. 

In this webinar expert speaker Steven Wachs, will clearly explain the steps to set-up a stability study and analyze the results to estimate the product's shelf life.

Session Highlights: 

  • Planning a Stability Study  Determining Performance Specifications 

  • Defining & Determining Shelf Life 

  • Confidence Levels 

  • Life Data Analysis Approach for Determining Shelf Life 

  • Life Data Analysis with Accelerated Aging 

  • Regression Modeling (Linear and Non-Linear) to Assess Stability/Shelf Life 

  • Pooling Batches for Stability Studies 

  • Validating Model Assumptions 

  • Handing Non-Normal Response Data 

  • Introduction to Accelerated Stability Testing 

  • Issues & Guidelines

Why You Should Attend: 

This webinar discusses the steps to set-up a stability study and analyzes the results to estimate the product's shelf life. The use of regression models to model the relationship between the response variable(s) and time are presented. Models useful for describing non-linear degradation over time are also presented. Additionally, methods for handling non-normal response data are also discussed. Finally, the use of accelerating variables to shorten the study time and the models required are introduced. The webinar includes several examples to illustrate the methods discussed.

Who Should Attend: 

  • R&D Personnel

  • Product Development Personnel 

  • Quality Personnel 

  • Lab Testing Personnel 

  • Operations / Production Managers 

  • Quality Assurance Managers, Engineers 

  • Processor Manufacturing Engineers or Managers 

  • Program or Product Managers
