Bayesian Estimation of Conditional Independence Graphs Improves Functional Connectivity Estimates. [PDF]

PLoS Computational Biology, 2015
Functional connectivity concerns the correlated activity between neuronal populations in spatially segregated regions of the brain, which may be studied using functional magnetic resonance imaging (fMRI).

Mind the Queue: A Case Study in Visualizing Heterogeneous Behavioral Patterns in Livestock Sensor Data Using Unsupervised Machine Learning Techniques

Frontiers in Veterinary Science, 2020
Sensor technologies allow ethologists to continuously monitor the behaviors of large numbers of animals over extended periods of time. This creates new opportunities to study livestock behavior in commercial settings, but also new methodological ...

randomLCA: An R Package for Latent Class with Random Effects Analysis

Journal of Statistical Software, 2017
Latent class is a method for classifying subjects, originally based on binary outcome data but now extended to other data types. A major difficulty with the use of latent class models is the presence of heterogeneity of the outcome probabilities within ...

A max-stable process model for rainfall extremes at different accumulation durations

Weather and Climate Extremes, 2016
A common existing approach to modeling rainfall extremes employs a spatial Bayesian hierarchical model, where latent Gaussian processes are specified on distributional parameters in order to pool spatial information.

A Directional-Linear Bayesian Network and Its Application for Clustering and Simulation of Neural Somas

IEEE Access, 2019
Neural somas perform most of the metabolic activities in the neuron and support the chemical process that generates the basic elements of the synapses, and consequently the brain activity.

Bayesian Covariance Structure Modeling of Responses and Process Data

Frontiers in Psychology, 2019
A novel Bayesian modeling framework for response accuracy (RA), response times (RTs) and other process data is proposed. In a Bayesian covariance structure modeling approach, nested and crossed dependences within test-taker data (e.g., within a testlet ...

What Is a Causal Graph?

Algorithms
This article surveys the variety of ways in which a directed acyclic graph (DAG) can be used to represent a problem of probabilistic causality. For each of these ways, we describe the relevant formal or informal semantics governing that representation ...
