The main goal of this book is to make more approachable the Bayesian econometric framework to students, researchers and practitioners who want to understand and apply this statistical/econometric approach, but who do not have time to develop programing skills. I tried to have a balance between applicability and theory. Then, this book comes with a very friendly graphical user interface (GUI) to implement the most common econometric models, but also contains the basic mathematical developments, as well as their code implementation, for those who are interested in advancing in more complex models.
