| 摘 要： | 令效用函数为代表性效用和随机项的乘积,给出了对应的分层Logit模型的具体表达式。进一步地,令效用函数是两者的和积混合,即代表性效用分解为两部分之和,随机项分解为两部分之积,两者相乘构成选择项的效用函数,推导出选择某方案的边际概率和相应的条件概率,从而大大拓展了分层Logit模型的类型和应用范围。

| Abstract: | In this paper,we propose a new function in which the summation of representative utility and random term is replaced by their multiplication,and derive a new NL model.Furthermore,letting the utility function be a mixture of summation and multiplication,namely the representative utility is decomposed into two added parts and the random term two multiplied parts,we derive the NL model and obain the marginal choice and conditional choice probabilities of an antenative.This study extends the NL mmodel applicati... |
