Sampling from Linear Multivariate Densities [PDF]
, 2009 It is well known that the generation of random vectors with non-independent components is difficult. Nevertheless, we propose a new and very simple generation algorithm for multivariate linear densities over point-symmetric domains.

New Algorithms for $M$-Estimation of Multivariate Scatter and Location [PDF]
, 2015 We present new algorithms for $M$-estimators of multivariate scatter and location and for symmetrized $M$-estimators of multivariate scatter. The new algorithms are considerably faster than currently used fixed-point and related algorithms. The main idea

Concentration of multivariate statistical tables [PDF]
Statistical Papers, 1992 The concentration of a data list \(x_ 1,\dots,x_ N\) of nonnegative numbers that sum up to 1, can be studied by its Lorenz diagram, defined by the origin and \(\bigl(k/N,\sum^ k_{i=1} x_{(i)}\bigr)\), \(i=1,\dots,N\), where \((x_{(1)},\dots,x_{(N)})\) is the sorted version of the list, and by its Gini coefficient.

Optimal and fast detection of spatial clusters with scan statistics [PDF]
, 2010 We consider the detection of multivariate spatial clusters in the Bernoulli model with $N$ locations, where the design distribution has weakly dependent marginals.
