Are bygones bygones?
Springer US (2012-08)This article reports an experiment which tests the principle of separability, i.e. that behaviour in a dynamic choice problem is independent of history and of unreachable eventualities. Although this is a well-known principle ... -
Estimating Space and Space-Time Covariance Functions for Large Data Sets: A Weighted Composite Likelihood Approach
American Statistical Association (2012)In the last years there has been a growing interest in the construction space-time covariance functions. However, effective estimation methods for these models are some- how unexplored. In this paper we propose a composite ... -
On potentially negative space time covariances obtained as sum of products of marginal ones
Springer Verlag (2008)Most of the literature on spatio-temporal covariance models proposes structures that are positive in the whole domain. However, problems of physical, biological or medical nature need covariance models allowing for ... -
Similarity measures of conditional intensity functions to test separability in multidimensional point processes
Springer-Verlag (2013-07)Separability in the context of multidimensional point processes assumes a multiplicative form for the conditional intensity function. This hypothesis is especially convenient since each component of a separable process may ... -
Some questions about Zadeh's extension on metric spaces
Elsevier (2018-10-29)For a continuous function f on a Hausdorff space X , we prove that [ ̂ f(u) ] α = f(u α ) for each u ∈ F (X) and α ∈[ 0 , 1 ] , where ̂ f is the Zadeh’s extension of f . By ...
