This book presents a selection of peer-reviewed contributions to the fifth Bayesian Young Statisticians Meeting, BaYSM 2021, held virtually due to the COVID-19 pandemic on 1-3 September 2021. Despite all the challenges of an online conference, the meeting provided a valuable opportunity for early career researchers, including MSc students, PhD students, and postdocs to connect with the broader Bayesian community.

The proceedings highlight many different topics in Bayesian statistics, presenting promising methodological approaches to address important challenges in a variety of applications. The book is intended for a broad audience of people interested in statistics, and provides a series of stimulating contributions on theoretical, methodological, and computational aspects of Bayesian statistics.

It reports the best work of young Bayesian statisticians It provides a quite large overview of the current research in the field It can be seen as a springboard for talented young Bayesian to write their first international paper

Autorentext

Raffaele Argiento is a Full Professor of Statistics at the Department of Economics of the University of Bergamo, Italy. He is member of Economics, Statistics and Data Science Ph.D board at the University of Milano-Bicocca and he is affiliated with the de Caströ Statistics initiative of the Collegio Carlo Alberto, Turin. His research focuses on Bayesian finite and infinite mixture models with a particular focus on the associated computational strategies as well as the related model based clustering. **
**Federico Camerlenghi is an Assistant Professor of Statistics at the Department of Economics, Management and Statistics and a board member of the Ph.D. in Economics, Statistics and Data Science at the University of  Milano-Bicocca, Italy. His research mainly focuses on the construction and investigation of Bayesian nonparameteric models to handle exchangeable and partially exchangeable data. He received the Savage award in Theory & Methods in 2017, and he was the chair of the junior Section of the International Society for Bayesian Analysis (j-ISBA) in 2019. 
Sally Paganin is a Research fellow in the Department of Biostatistics at Harvard T.H. Chan School of Public Health, and treasurer of the junior Section of the International Society for Bayesian Analysis (j-ISBA). Previously, she was a Postdoctoral Researcher at UC Berkeley, and a core team member of the NIMBLE software project. Her research focuses on Bayesian methods and statistical models for complex data, along with the development of statistical software and algorithms.
