| dc.description.abstract | Using nominal variables with many levels as predictors in statistical modelling can be a difficult task. Ways to group the levels of such variables optimally becomes of special interest. In this work we propose a procedure and a tool implemented in R language to deal with this type of situation, in order to create an optimally-recategorized variable to modelling or simply for descriptive purposes. An example with a real data in Insurance environment will be conducted to illustrate the performance, as well the advantages and disadvantages. | pt_PT |
