Monte Carlo inference for semiparametric Bayesian regression

no code implementations8 Jun 2023 Daniel R. Kowal, Bohan Wu

Data transformations are essential for broad applicability of parametric regression models.

Gaussian Processes regression

Bayesian adaptive and interpretable functional regression for exposure profiles

1 code implementation1 Mar 2022 Yunan Gao, Daniel R. Kowal

Leveraging the proposed modeling, computational, and decision analysis framework, we conclude that prenatal $\mbox{PM}_{2. 5}$ exposure during early and late pregnancy is most adverse for 4th end-of-grade reading scores.

Warped Dynamic Linear Models for Time Series of Counts

1 code implementation27 Oct 2021 Brian King, Daniel R. Kowal

However, the options for count time series are limited: Gaussian DLMs require continuous data, while Poisson-based alternatives often lack sufficient modeling flexibility.

Semiparametric discrete data regression with Monte Carlo inference and prediction

1 code implementation23 Oct 2021 Daniel R. Kowal, Bohan Wu

These data commonly exhibit complex distributional features such as zero-inflation, over-/under-dispersion, boundedness, and heaping, which render many parametric models inadequate.

Subset selection for linear mixed models

no code implementations27 Jul 2021 Daniel R. Kowal

We introduce a Bayesian decision analysis for subset selection with LMMs.

Semiparametric count data regression for self-reported mental health

no code implementations16 Jun 2021 Daniel R. Kowal, Bohan Wu

STAR is deployed to study the factors associated with self-reported mental health and demonstrates substantial improvements in goodness-of-fit compared to existing count data regression models.

Bayesian subset selection and variable importance for interpretable prediction and classification

no code implementations20 Apr 2021 Daniel R. Kowal

Given any Bayesian predictive model $\mathcal{M}$, we extract a family of near-optimal subsets of variables for linear prediction or classification.

Fast, Optimal, and Targeted Predictions using Parametrized Decision Analysis

no code implementations23 Jun 2020 Daniel R. Kowal

Instead, we design a class of parametrized actions for Bayesian decision analysis that produce optimal, scalable, and simple targeted predictions.

Simultaneous Transformation and Rounding (STAR) Models for Integer-Valued Data

1 code implementation27 Jun 2019 Daniel R. Kowal, Antonio Canale

We propose a simple yet powerful framework for modeling integer-valued data, such as counts, scores, and rounded data.

Dynamic Function-on-Scalars Regression

1 code implementation5 Jun 2018 Daniel R. Kowal

We develop a modeling framework for dynamic function-on-scalars regression, in which a time series of functional data is regressed on a time series of scalar predictors.
