In econometric studies, for example, the ridit scores measuring taste survey answers of a competing or historically important product are often used as the reference data set against which taste surveys of new products are compared.
Intuitively, ridit scores can be understood as a modified notion of percentile ranks.
Ridit scoring has found use primarily in the health sciences (including nursing and epidemiology) and econometric preference studies.
[citation needed] Besides having intuitive appeal, the derivation for ridit scoring can be arrived at with mathematically rigorous methods as well.
Brockett and Levine[2] presented a derivation of the above ridit score equations based on several intuitively uncontroversial mathematical postulates.
