A Latent Class Binomial Logit Methodology for the Analysis of Paired Comparison Choice Data
开发了一种潜在类别模型，用于识别配对比较选择实验中的被试类别，同时估计不同组别的Logit系数，并通过消费者风险感知实验验证了方法的预测效度和对减少比较次数的敏感性。
ABSTRACT A latent class model for identifying classes of subjects in paired comparison choice experiments is developed. The model simultaneously estimates a probabilistic classification of subjects and the logit models' coefficients relating characteristics of objects to choices for each respective group among two alternatives in paired comparison experiments. A modest Monte Carlo analysis of algorithm performance is presented. The proposed model is illustrated with empirical data from a consumer psychology experiment that examines the determinants of perceived consumer risk. The predictive validity of the method is assessed and compared to that of several other procedures. The sensitivity of the method to (randomly) eliminate comparisons, which is important in view of reducing respondent fatigue in the task, is investigated.
