摘要：

In this article we discuss the identifiability of a probability model which has been proven useful for capturing the main features of ordinal data generated by rating surveys. Specically, we show that the mixture of a shifted Binomial and a Uniform discrete distribution is identifiable when the number of categories is greater than three
