A Model-Based fMRI Analysis with Hierarchical Bayesian Parameter Estimation.

A recent trend in decision neuroscience is the use of model-based fMRI using mathematical models of cognitive processes. However, most previous model-based fMRI studies have ignored individual differences due to the challenge of obtaining reliable parameter estimates for individual participants. Meanwhile, previous cognitive science studies have demonstrated that hierarchical Bayesian analysis ...

A Hierarchical Bayesian Approach for Parameter Estimation in HIV Models

A hierarchical Bayesian approach is developed to estimate parameters at both the individual and the population level in a HIV model, with the implementation carried out by Markov Chain Monte Carlo (MCMC) techniques. Sample numerical simulations and statistical results are provided to demonstrate the feasibility of this approach.

How to improve parameter estimates in GLM-based fMRI data analysis: cross-validated Bayesian model averaging

In functional magnetic resonance imaging (fMRI), model quality of general linear models (GLMs) for first-level analysis is rarely assessed. In recent work (Soch et al., 2016: "How to avoid mismodelling in GLM-based fMRI data analysis: cross-validated Bayesian model selection", NeuroImage, vol. 141, pp. 469-489; http://dx.doi.org/10.1016/j.neuroimage.2016.07.047), we have introduced cross-valida...

Bayesian Spectrum Analysis and Parameter Estimation

Bayesian spectrum analysis is still in its infancy. It was born when E. T. Jaynes derived the periodogram [2] as a su cient statistic for determining the spectrum of a time sampled data set containing a single stationary frequency. Here we extend that analysis and explicitly calculate the joint posterior probability that multiple frequencies are present, independent of their amplitude and phase...

Parameter Estimation in a Hierarchical Model for Species Occupancy

In this paper, we describe a model for the relationship between the occupancy pattern of a species on a landscape and imperfect observations of its presence or absence. The structure in the observation process is incorporated generatively, and environmental inputs are incorporated discriminatively. Our experiments on synthetic data compare two methods for training this model under various regul...
