Abstract

fetched live from OpenAlex

The paper proposes a closed-form joint econometric model of Stated Preference (SP) choices and corresponding confidence rating elicitation through the measure of choice model entropy functions. The proposed econometric model is estimated empirically by using two SP survey datasets collected in Vancouver and Toronto. Empirical models reveal that the SP choice task’s complexity directly influences SP confidence ratings, and there is an endogenous relationship between them. It is clear that capturing such endogeneity does improve the parameter estimates of choice model components. The most important improvements are the increases in statistical significances of choice model parameters in the joint model, some of which may be even insignificant in the univariate choice model. Moreover, evidence ignoring such endogeneity may cause under-estimation of the marginal rate of substitutions of the SP choice attributes. However, the level and extant of such benefit gains vary by the nature and types of SP experiments.

Full frame distilled prediction

Teacher imitation

Not 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.
