Spatial Autoregressive Models for Scan Statistic
Mohamed-Salem Ahmed, Lionel Cucala, Michael Genin
Spatial scan statistics are well-known methods for cluster detection and are widely used in epidemiology and medical studies for detecting and evaluating the statistical significan…
Classifying variable-structures: a general framework
Xavier Bry, Lionel Cucala
In this work, we unify recent variable-clustering techniques within a common geometric framework which allows to extend clustering to variable-structures, i.e. variable-subsets wit…
Adaptive ABC model choice and geometric summary statistics for hidden Gibbs random fields
Julien Stoehr, Pierre Pudlo, Lionel Cucala
Selecting between different dependency structures of hidden Markov random field can be very challenging, due to the intractable normalizing constant in the likelihood. We answer th…
A Bayesian reassessment of nearest-neighbour classification
Lionel Cucala, Jean-Michel Marin, Christian Robert +1
The k-nearest-neighbour procedure is a well-known deterministic method used in supervised classification. This paper proposes a reassessment of this approach as a statistical techn…
Le Cam spacings theorem in dimension two
Lionel Cucala
The definition of spacings associated to a sequence of random variables is extended to the case of random vectors in [0,1]^2. Beirlant & al. (1991) give an alternative proof of the…
