We concentrate on characteristics of minima XN from samples of iid lognormals X1i ∼ 2pLND. We demonstrate that the distribution of XN for 2 ≤ N ≤ 1,000 may be fitted more accurately by 2pLND than by the limiting Gumbel distribution. An extended

Principal points of a distribution have been introduced by Flury [1] who tackled the problem of optimal grouping in multivariate data. In essence, principal points are the theoretical counterparts of cluster means obtained by a k-means clustering alg

We report on both theoretical developments and comutational experience with the patchwork rejection technique in Zechner and Stadlober [1993] and Zechner [1997]. The basic approach is due to Minh [1988], who suggested a special sampling method for th
