ACA/HB Module for Hierarchical Bayes Estimation
In the last few years, leading academics have developed a new
technique for estimating conjoint utilities called Hierarchical Bayes (HB).
HB significantly improves conjoint analysis results. While improvements
are most dramatic for traditional conjoint (CVA) and choice-based
methods (CBC), ACA also benefits from HB estimation.
ACA/HB provides the following benefits:
The ACA/HB module improves the quality of each individual's utility
estimates by "borrowing" information from other individuals. This
translates to more accurate predictions of both individual choices and
ACA has been criticized because of potential scale incompatibilities
between the self-explicated priors and conjoint pairs segments of the
interview. ACA/HB provides a more theoretically sound way of combining
data from these two sections of the interview. Not only is the technique
more defensible, but the results are generally better.
ACA/HB does a better job of estimating utilities for the levels not
taken forward into pairs when using "Most Likelies" and "Unacceptables."
ACA/HB requires Windows XP or later.
