Temporal Variety in Consumer Behavior
开发了一个衡量时间多样性的指标，并作为因变量研究三类产品中个人购买行为的变异性，用预测变量刻画高/低购买变异的个体特征并对保留样本分类。
A measure of temporal variety is developed and is used as a dependent variable in an investigation of the variability in individual purchases from three product classes. Predictor variables are used to characterize individuals who exhibit higher versus lower levels of purchase variability and to classify a holdout sample.
