A Proportional Random Utility Approach to Qualitative Response Models
提出一种新的定性响应模型响应概率函数形式，避免多项逻辑回归的无关选项独立性约束，计算比多项概率回归更简单，适用于中等数量选项的问题分析。
A new functional form of the response probability for a qualitative response model is proposed. The new model is flexible enough to avoid the constraint of independence from irrelevant alternatives, which is perceived as a weakness of the multinomial logit model in some applications. It is computationally simpler than the multinomial probit model and is promising for analyzing problems with a moderate number of alternatives.
