| Abstract: | Sometimes a larger dataset needs to be reduced to just a few points, and it is desirable that these points be representative
of the whole dataset. If the future uses of these points are not fully specified in advance, standard decision-theoretic approaches
will not work. We present here methodology for choosing a small representative sample based on a mixture modeling approach. |
