Modeling insurance claims using Bayesian nonparametric regression. [PDF]

PLoS ONE
Predicting future insurance claims using observed covariates is essential for actuaries in setting appropriate insurance premiums. For this purpose, actuaries commonly employ parametric regression models, which assume the same functional form tying the ...

Bayesian nonparametric method for genetic dissection of brain activation region [PDF]

Frontiers in Neuroscience, 2023
Biological evidence indicewates that the brain atrophy can be involved at the onset of neuropathological pathways of Alzheimer's disease. However, there is lack of formal statistical methods to perform genetic dissection of brain activation phenotypes ...

A Bayesian nonparametric method for jointly clustering multiple spatial transcriptomic datasets and simultaneous gene selection [PDF]

Scientific Reports
In spatial transcriptomics, many algorithms are available for clustering cells into groups based on gene expression and location, although not without limitations. Such limitations include having to know the number of clusters, limiting inference to only

Nonparametric Bayesian Networks as a Tool of Multiscale Time Series Analysis and Remote Sensing Data Integration

Известия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. Nonparametric Bayesian networks are a promising tool for analyzing, visualizing, interpreting and predicting the structural and dynamic characteristics of complex systems. Modern interdisciplinary research involves the complex processing of

Bayesian Analysis of Tweedie Compound Poisson Partial Linear Mixed Models with Nonignorable Missing Response and Covariates

Entropy, 2023
Under the Bayesian framework, this study proposes a Tweedie compound Poisson partial linear mixed model on the basis of Bayesian P-spline approximation to nonparametric function for longitudinal semicontinuous data in the presence of nonignorable missing

Bayesian Analysis for Penalized Spline Regression Using WinBUGS

Journal of Statistical Software, 2005
Penalized splines can be viewed as BLUPs in a mixed model framework, which allows the use of mixed model software for smoothing. Thus, software originally developed for Bayesian analysis of mixed models can be used for penalized spline regression ...

Bayesian model averaging for nonparametric discontinuity design.

PLoS ONE, 2022
Quasi-experimental research designs, such as regression discontinuity and interrupted time series, allow for causal inference in the absence of a randomized controlled trial, at the cost of additional assumptions.

qgam: Bayesian Nonparametric Quantile Regression Modeling in R

Journal of Statistical Software, 2021
Generalized additive models (GAMs) are flexible non-linear regression models, which can be fitted efficiently using the approximate Bayesian methods provided by the mgcv R package.

Bayesian nonparametric duration model with censorship

Statistica, 2007
This paper is concerned with nonparametric i.i.d. durations models censored observations and we establish by a simple and unified approach the general structure of a bayesian nonparametric estimator for a survival function S.

Model Selection for High Dimensional Nonparametric Additive Models via Ridge Estimation

Mathematics, 2022
In ultrahigh dimensional data analysis, to keep computational performance well and good statistical properties still working, nonparametric additive models face increasing challenges.
