SPATIAL DEPENDENCE IN OPTION OBSERVATION ERRORS
Econometric Theory, 2020 In this paper, we develop the first formal nonparametric test for whether the observation errors in option panels display spatial dependence. The panel consists of options with different strikes and tenors written on a given underlying asset. The asymptotic design is of the infill type—the mesh of the strike grid for the observed options shrinks ...

Modeling spatial tail dependence with Cauchy convolution processes
, 2022 We study the class of dependence models for spatial data obtained from Cauchy convolution processes based on different types of kernel functions. We show that the resulting spatial processes have appealing tail dependence properties, such as tail ...

A Classification for a Geostatistical Index of Spatial Dependence
Revista Brasileira de Ciência do Solo: In geostatistical studies, spatial dependence can generally be described by means of the semivariogram or, in complementary form, with a single index followed by its categorization to classify the degree of such dependence.

Spatial Parrondo games with spatially dependent game $A$
CoRR, 2020 Parrondo games with spatial dependence were introduced by Toral (2001) and have been studied extensively. In Toral's model, $N$ players are arranged in a circle. The players play either game $A$ or game $B$. In game $A$, a randomly chosen player wins or loses one unit according to the toss of a fair coin.

Incidence of Phytophthora infestans (Mont.) de Bary on potato and tomato in Maine, 2006–2010
Journal of Plant Protection Research, 2015 Late blight, caused by Phytophthora infestans (Mont.) de Bary, is a devastating disease which is found worldwide. In Maine, United States (US), we recorded late blight on potato and tomato during the 2006-2009 cropping seasons. From 2006 to 2008, over 90%
