Analytic Derivatives Discrete-Choice Dynamic Programming Models
2015/9/18
This paper shows how to recursively calculate analytic first and second derivatives of the likelihood function generated by a popular version of a discrete-choice, dynamic programming model, allowing ...
Asymmetries in Ordered Strength of Preference Models: Implications of Focus Shift for Discrete-Choice Preference Estimation
preference model survey design
2011/10/23
This paper explores potential focus shift asymmetries in an ordered strength of preference model applied to contingent choice data. A focus shift occurs when respondents weight factors differently whe...
