Your role

Topic  – Experimental design

iAt the Sawtooth Conference of 2009, SKIM presented the paper “Benefits of Deviating from Orthogonal Designs”.

iiThis paper discussed creating experimental designs within Choice-Based Conjoint. iiiContrary to contemporary beliefs, the paper demonstrated that it is sometimes beneficial to deviate from orthogonal designs. Most particularly, if the primary aim of a survey is to provide predictions of line pricing scenarios, then it is beneficial to include line pricing scenarios in the experimental design as well.

In the discussions at various later conferences, various academics and practitioners are still divided in two groups with different beliefs: one group who believes it is very important to keep the experimental design as close to orthogonality as possible, and another group who does not care too much about orthogonality and rather believes it is very important to keep the experimental design very close to the particular predictions for which a survey has been set up.

We are looking for an intern who is willing to provide a broader perspective on this debate.

It is not straightforward to assess who is right here, because utility estimations in Choice-Based Conjoint are usually based on Bayesian statistics. A prediction of any scenario does not come with a standard error as in classical statistics.

In practice the accuracy of predictions is mostly assessed by calculating hit rates in so-called holdout tasks and (occasionally) by comparing the MAE between predictions and actual responses in holdout tasks, but both are pretty poor measures of prediction accuracy.
