A second-order test to detect spatio-temporal anisotropic effects in point patterns
Taylor & Francis (2018)Second-order spatio-temporal orientation methods provide a natural tool for the analysis of anisotropic spatio-temporal point process data. In this paper, we generalize a method based on the spatial point pair orientation ... -
Models of covariance functions of gaussian random fields escaping from isotropy, stationarity and non negativity
International Society for Stereology (2014-01)This paper represents a survey of recent advances in modeling of space or space-time Gaussian Random Fields (GRF), tools of Geostatistics at hand for the understanding of special cases of noise in image analysis. They can ... -
On new families of anisotropic spatial log-Gaussian Cox processes
Springer (2020)Cox processes are natural models for point process phenomena that are environmentally driven, but much less natural for phenomena driven primarily by interactions amongst the points. The class of log-Gaussian Cox processes ... -
Second-order analysis of anisotropic spatiotemporal point process data
Wiley (2015-02)Second-order orientation methods provide a natural tool for the analysis of spatial point process data. In this paper, we extend to the spatiotemporal setting the spatial point pair orientation distribution function. The ... -
Spatial threshold exceedance analysis through marked point processes
Wiley- Blackwell (2012)Indicators of recurrence, persistence and, in general, distribution patterns of extremal events defined by random field threshold exceedances provide relevant information on critical phenomena for risk assessment. Such ...
