Modeling Preferences for Common Attributes in Multicategory Brand Choice
Bibliographic record
Abstract
The authors propose a multicategory brand choice model based on the conceptualization that the intrinsic utility for a brand is a function of underlying attributes, some of which are common across categories. The premise is that household preferences for attributes that are common across categories are likely to be correlated. The model that the authors develop projects the unobserved preferences for attributes to a lower dimensional space of unobserved factors. The factors are interpretable as household “traits” that transcend categories, and they can be used to predict preferences for attributes in new categories. The authors apply the proposed model to household panel data for three closely related snack categories and for two less-related food categories. The authors find strong correlations in preferences for product attributes such as brand names and low fat or fat free. This study demonstrates that these high correlations in product attribute preferences across categories are useful in targeting activities in existing and new categories.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
