چکیده

A central theme of systems neuroscience is to characterize the tuning of neural responses to sensory 12 stimuli or the production of movement. Statistically, we often want to estimate the parameters of the 13 tuning curve, such as preferred direction, as well as the associated degree of uncertainty, characterized 14 by errorbars. Here we present a new sampling-based, Bayesian method that allows the estimation of 15 tuning curve parameters, the estimation of error bars, and hypothesis testing. This method also provides 16 a useful way of visualizing which tuning curves are compatible with the recorded data. We demonstrate 17 the utility of this approach using recordings of orientation and direction tuning in primary visual cortex, 18 direction of motion tuning in primary motor cortex, and simulated data. 19 20

Spatial count models on the number of unhealthy days in Tehran

Spatial count data is usually found in most sciences such as environmental science, meteorology, geology and medicine. Spatial generalized linear models based on poisson (poisson-lognormal spatial model) and binomial (binomial-logitnormal spatial model) distributions are often used to analyze discrete count data in which spatial correlation is observed. The likelihood function of these models i...

Structural Equation Modeling-Based Bayesian Method for Hierarchical Model Validation

Model validation involves quantitatively comparing model predictions with experimental observations, both of which contain uncertainty. A building block approach to model validation may proceed through various levels, such as material to component to subsystem to system. This paper presents a structural equation modeling-based Bayesian approach to make use of the low-level data for system-level...

eqr094: Hierarchical MCMC for Bayesian System Reliability

Hierarchical models are one of the central tools of Bayesian analysis. They offer many advantages, including the ability to borrow strength to estimate individual parameters and the ability to specify complex models that reflect engineering and physical realities. Markov chain Monte Carlo is a set of algorithms that allow Bayesian inference in a variety of models. We illustrate hierarchical mod...

ggmcmc: Analysis of MCMC Samples and Bayesian Inference

ggmcmc is an R package for analyzing Markov chain Monte Carlo simulations from Bayesian inference. By using a well known example of hierarchical/multilevel modeling, the article reviews the potential uses and options of the package, ranging from classical convergence tests to caterpillar plots or posterior predictive checks. This R vignette is based on the article published at the Journal of St...

Bayesian change point estimation in Poisson-based control charts

Precise identification of the time when a process has changed enables process engineers to search for a potential special cause more effectively. In this paper, we develop change point estimation methods for a Poisson process in a Bayesian framework. We apply Bayesian hierarchical models to formulate the change point where there exists a step < /div> change, a linear trend and a known multip...

Hierarchical Bayesian Modeling of Human Decision-Making Using Wiener Diffusion

Wiener diffusion accounts of human decision-making are among the most successful and best developed formal models in the psychological sciences. We reconsider these models from a Bayesian perspective, using graphical modeling, and Markov Chain Monte-Carlo methods for posterior sampling. By analyzing seminal data from a brightness discrimination task, we show how the Bayesian approach offers sev...
