## Abstract

Research in psychology generates interesting data sets and unique statistical modelling tasks. However, these tasks, while important, are often very specific, so appropriate statistical models and methods cannot be found in accessible Bayesian tools. As a result, the use of Bayesian methods is limited to those that have the technical and statistical fundamentals that are required for probabilistic programming. Such knowledge is not part of the typical psychology curriculum and is a difficult obstacle for psychology students and researchers to overcome. The goal of the bayes4psy package is to bridge this gap and offer a collection of models and methods to be used for data analysis that arises from psychology experiments and as a teaching tool for Bayesian statistics in psychology. The package contains Bayesian t-test and bootstrapping and models for analyzing reaction times, success rates, and colors. It also provides all the diagnostic, analytic and visualization tools for the modern Bayesian data analysis workflow.
