Bias-Correction and Test for Mark-Point Dependence with Replicated Marked Point Processes
Journal of the American Statistical Association, 2022 Mark-point dependence plays a critical role in research problems that can be fitted into the general framework of marked point processes. In this work, we focus on adjusting for mark-point dependence when estimating the mean and covariance functions of the mark process, given independent replicates of the marked point process.

Stochastic Modeling of Trees in Forest Environments
IEEE Access, 2021 Our article deals with the detection and model generation of complex objects with curvilinear parts, like trees, with stochastic relaxation. The proposed algorithm can rely on any initial estimation of object parts as a probability map (like those ...

A copula model for marked point processes [PDF]
Lifetime Data Analysis, 2013 Many chronic diseases feature recurring clinically important events. In addition, however, there often exists a random variable which is realized upon the occurrence of each event reflecting the severity of the event, a cost associated with it, or possibly a short term response indicating the effect of a therapeutic intervention.

IEEE Access, 2023 Multiple state variables governed by internal processes within the human body remain unobserved. On a number of occasions, these states are linked to point process bioelectric and biochemical observations coupled together with continuous-valued variables.

A method for generating stand structures using Gibbs marked point process
Silva Fennica, 2002 Stand growth modelling based on single tree responses to their surroundings requires a description of the spatial structure of a stand. While such detailed information is rarely available from field measurements, a method to create it from more general ...

A stochastic marked point process model for earthquakes [PDF]
Natural Hazards and Earth System Sciences, 2003 A simplified stochastic model for earthquake occurrence focusing on the spatio-temporal interactions between earthquakes is presented. The model is a marked point process model in which each earthquake is represented by its magnitude and coordinates ...

A Marked Point Process for Modeling Lidar Waveforms [PDF]
IEEE Transactions on Image Processing, 2010 Lidar waveforms are 1-D signals representing a train of echoes caused by reflections at different targets. Modeling these echoes with the appropriate parametric function is useful to retrieve information about the physical characteristics of the targets.
