[HTML][HTML] First passage times of two-dimensional correlated processes: Analytical results for the Wiener process and a numerical method for diffusion processes

L Sacerdote, M Tamborrino, C Zucca - Journal of Computational and …, 2016 - Elsevier
Given a two-dimensional correlated diffusion process, we determine the joint density of the
first passage times of the process to some constant boundaries. This quantity depends on …

Mixed vine copulas as joint models of spike counts and local field potentials

A Onken, S Panzeri - Advances in Neural Information …, 2016 - proceedings.neurips.cc
Concurrent measurements of neural activity at multiple scales, sometimes performed with
multimodal techniques, become increasingly important for studying brain function. However …

A copula-based method to build diffusion models with prescribed marginal and serial dependence

E Bibbona, L Sacerdote, E Torre - Methodology and computing in applied …, 2016 - Springer
This paper investigates the probabilistic properties that determine the existence of space-
time transformations between diffusion processes. We prove that two diffusions are related …

Joint analysis of spikes and local field potentials using copula

M Hu, M Li, W Li, H Liang - NeuroImage, 2016 - Elsevier
Recent technological advances, which allow for simultaneous recording of spikes and local
field potentials (LFPs) at multiple sites in a given cortical area or across different areas, have …
