Open AccessAn encoding approach for stable change point detection
Without imposing prior distributional knowledge underlying multivariate time series of interest, we propose a nonparametric change-point detection approach to estimate the number of change points and their loc...

Open AccessThe geometry of colors in van Gogh’s Sunflowers
“Paintings fade like flowers”: van Gogh’s prediction on the impact of age on paintings came true for most of his paintings. We have studied the consequences of this aging on the Sunflowers in a vase with a yellow...

Using Clustering to Examine Inter-individual Variability in Topography of Auditory Event-Related Potentials in Autism and Typical Development
Although prior studies have compared sensory event-related potential (ERP) responses between groups of autistic and typically-develo** participants, it is unclear how heterogeneity contributes to the results...

Open AccessDefining clusters of young autistic and typically develo** children based on loudness-dependent auditory electrophysiological responses
Autistic individuals exhibit atypical patterns of sensory processing that are known to be related to quality of life, but which are also highly heterogeneous. Previous investigations of this heterogeneity have...

On Association Study of Scalp EEG Data Channels Under Different Circumstances
Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain using different electrodes, which are considered as the EEG channels that are placed on scal...

Does niche-overlap facilitate mixed-species flocking in birds?
Foraging niche overlap between attendant species and the nuclear species of mixed-species flocks may induce competition as well as facilitation. In this study, we hypothesized that canopy species would appear ...

A Network Approach for Evaluating Coherence in Multivariate Systems: An Application to Psychophysiological Emotion Data
We present an approach for evaluating coherence in multivariate systems that considers all the variables simultaneously. We operationalize the multivariate system as a network and define coherence as the effic...

Statistical modeling and inferences on dynamic decision-making mechanism underlying longitudinal distribution data with resource heterogeneity
We propose a new way of constructing dynamic decision-making model and a nonlikelihood based statistical approach for analyzing a new data type: longitudinal distribution data. This longitudinal data records a...

Open AccessExploring the Dynamics of Dyadic Interactions via Hierarchical Segmentation
In this article we present an exploratory tool for extracting systematic patterns from multivariate data. The technique, hierarchical segmentation (HS), can be used to group multivariate time series into segme...

Validation of A Heteroscedastic Hazards Regression Model
A Cox-type regression model accommodating heteroscedasticity, with a power factor of the baseline cumulative hazard, is investigated for analyzing data with crossing hazards behavior. Since the approach of par...

Comparison of the efficacy of tropisetron versus a metoclopramide cocktail based on the intensity of cisplatin-induced emesis
Cisplatin-induced emesis is one of the most feared side effects in cancer treatment. High-dose metoclopramide may prevent only 30–40% of cases of acute emesis. Investigations to test the efficacy of new antiem...
