Statistical Procedures for Fuzzy Data in Medical Research

In medical research, there has been an increasing interest in statistical analysis of inherently imprecise, uncertain, or linguistic observations such as perceived breathlessness, general fatigue, or self images. Fuzzy sets can effectively encode them, and a variety of statistical procedures have been developed to analyze fuzzy data. In this paper, we review some of the procedures and explain how they can be applied to medical research.
