A method of possible equivalence classes, described in [14], is extended under non-deterministic information. The method considers both indiscernibility and discernibility of non-deterministic values by using possible equivalence classes. As a result, the method gives the same results as the method of possible worlds. Furthermore, maximal possible equivalences are introduced in order to effectively calculate rough approximations. We can use the method of possible equivalence classes to obtain rough approximations between arbitrary sets of attributes containing non-deterministic values.
