Abstract
We address the problem of clustering individuals described with several mixed variables divided in homogeneous blocks. We propose a hierarchical method with two levels to partition the individuals. The method is based on two successive steps using mixed topological maps combined with agglomerative hierarchical clustering. The proposed approach allows to take into account simultaneously qualitative and quantitative variables as well as the variable blocking. A real example on indoor air quality illustrates the proposed method.
