Power law distribution in education: Effect of economical, teaching, and study conditions in university entrance examination
(World Scientific Publ Co Pte Ltd, 2003-05-01)
We studied the statistical distribution of student's performance, which is measured through their marks, in university entrance examination (Vestibular) of UNESP (Universidade Estadual Paulista) with respect to (i) period ...

The gradually truncated Levy flight for systems with power-law distributions
(Elsevier B.V., 1999-06-01)
Power-law distributions have been observed in various economical and physical systems. Levy flights have infinite variance which discourage a physical approach. We introduce a class of stochastic processes, the gradually ...
Perfectly random sampling of truncated multinormal distributions
(Applied Probability Trust, 2007-12)
The target measure mu is the distribution of a random vector in a box B, a Cartesian product of bounded intervals. The Gibbs sampler is a Markov chain with invariant measure mu. A 'coupling from the past' construction of ...
