May Luncheon

 

Location: Virtual (Zoom) | Chicago, Illinois

 

Date: Thursday, May 15, 2025 12:00 PM (Central Standard Time)

 

Luncheon Abstract:

 

Choice-based conjoint (CBC) experiments are widely used to understand consumer preferences and willingness to pay for different product features. One important consideration in designing CBC experiments is the balance of attribute levels across the design. Implementing this strategy seeks to give every level an equal chance to influence the respondent’s decision in the conjoint design.

 

But does that strategy work in every case?

In this lunch & learn, we'll revisit the work of Huber and Zwerina (1996) to determine if utility-balanced designs, a design strategy that trades off on level balance while optimizing which alternatives are paired against each other within tasks, could result in better predictions at the individual level.

 

Spoiler Alert - We'll show that utility-balanced designs perform well in predicting data from both utility-balanced and non-utility-balanced designs (using real respondents!) and that those respondents do not seem to be fatigued by utility-balanced designs. This would suggest that utility-balanced designs could be a successful strategy depending on the attributes and levels being tested!

President's Letter

 

Dear Members,

 

Over the past nine months, the Chicago Chapter of the American Statistical Association has had the privilege of hosting a series of outstanding presentations and events. We organized four virtual and two in-person sessions, all delivered by exceptional speakers who are leaders in their respective fields.

 

We have one event remaining this year: Megan Peitz, an expert in conjoint analysis and founder of Numerios, will deliver what promises to be a fascinating presentation on Survey Design and Analysis. We encourage you to attend and look forward to an engaging discussion.

 

In addition to these sessions, we held two major in-person events:

 

·    The awarding of the 2024 Chicago ASA Statistician of the Year honor to Dr. James Berger.

 

·    Our recent conference on Modern Forecasting Methods

 

It has truly been a remarkable year, and I have been honored to serve as President of the Chicago Chapter. As my term comes to an end, I want to sincerely thank each of you for your membership, engagement, and support of our chapter’s activities.

 

Wishing you all the best,

Joe Retzer

President (and soon to be Past President)

Chicago Chapter of the American Statistical Association
