Mixed Logit with Repeated Choices: Households' Choices of Appliance Efficiency Level
介绍混合Logit模型（随机参数Logit或误差成分Logit），它克服了标准Logit的IIA限制，能处理同一消费者重复选择中的相关性。并用该模型分析家庭在公用事业补贴项目下对高效电器的选择。
Mixed logit models, also called random-parameters or errorcomponents logit, are a generalization of standard logit that do not exhibit the restrictive "independence from irrelevant alternatives" property and explicitly account for correlations in unobserved utility over repeated choices by each customer. Mixed logits are estimated for households' choices of appliances under utility-sponsored programs that offer rebates or loans on high-efficiency appliances. © 1998 by the President and Fellows of Harvard College and the Massachusetts Institute of Technolog
