Sažetak
In this paper we consider a clustering problem for a data-points set
$\mathcal{A}$ into disjoint nonempty subsets - clusters, whereby
it is assumed that elements of the set $\mathcal{A}$ are determined by
one or two characteristics. Least square criteria and least absolute deviation criteria are used for
solving the problem. A number of examples illustrating differences
between these criteria are given. Corresponding software support is
developed for the purpose of facilitating scientific or professional
work by using this methodology and approach.
