Abstract
Moving from the original work of Zani (1982), in thispaper we propose new weighted similarity indexes for variableswith multiple categories. In contrast to traditional measures,these indexes also consider the frequency of the modalities ofeach attribute in the sample and the possible association betweenpairs of variables. The suitability of the indexes is shownthrough an application in marketing.
