Regularity Analysis and its Applications in Data Miningful tool not only for concept description. It is also indispensable for various applications like classification or decomposition. In this Chapter we present also the applications of data regularity to three basic problems of data mining: classification, data description and data decomposition.

Statistical Techniques for Rough Set Data Analysisthe — stated or unstated — model assumptions. The question arises, whether there is a step in the modelling process which is informative for the researcher and, at the same time, does not require additional assumptions about the data. To make this clearer, we follow [9] in assuming that a data model consists of
