On the spatial correlation between areas of high coseismic slip and aftershock clusters of the Maule earthquake Mw=8.8
Nonparametric clustering Kernel density estimation Maule 2010 Earthquake aftershock distribution slip model.

We study the spatial distribution of clusters associated to the aftershocks of the megathrust Maule earthquakeMW8.8 of 27 February 2010. We used a recent clustering method which hinges on a nonparamet...

This paper investigates how market concentration affects research activity in an
economic cluster. The firms in the cluster play a two-stage game. In the first stage the firms
choose whether or not ...
Optimal and fast detection of spatial clusters with scan statistics
Scan statistic Bernoulli model optimal detection multiscaleinference fast algorithm concentration inequality
2010/3/10
We consider the detection of multivariate spatial clusters in the
Bernoulli model with N locations, where the design distribution has
weakly dependent marginals. The locations are scanned with a rec...
How many clusters?

The title poses a deceptively simple question that must be addressed by
any statistical model or computational algorithm for the clustering of points. Two
distinct interpretations are possible, one ...
Random Walk Attracted by Percolation Clusters
subcritical percolation subdiffusivity reversibility spectral gap
2009/4/27
Starting with a percolation model in Zd in the subcritical regime, we consider a random walk described as follows: the probability of transition from x to y is proportional to some function f of the s...
