Ockham's razor in interval identification

Since real-life measurements cannot be absolutely precise, we never know the precise value of a physical quantity, we only know an interval of its ix~ssible values. Due m this uncertainty, there are several different models that are consistent with the same measurement results. Which model should we ch(x~se? in this paper, we show that Ockham's raz~w principle (Emitim 4umld m~t be m~dtiplial ~anwe.eawu'~/y) (an lead to a natural criterion for choosing a mlxtel. As an example, we apply this criterion to data processing related to a reasonably simple psychological problem.
