Welcome to ISBA!

The International Society for Bayesian Analysis (ISBA)  was founded in 1992 to promote the development and application of Bayesian analysis useful in the solution of theoretical and applied problems in science, industry and government. By sponsoring and organizing meetings, publishing the electronic journal of Bayesian statistics Bayesian Analysis, and other activities ISBA provides a focal point for those interested in Bayesian analysis and its applications.  For an interesting historical perspective, Arnold Zellner recaps the beginnings of ISBA. 

ISBA 2016 World Meeting

The ISBA 2016 World Meeting will be held at the Forte Village Resort, Sardinia, Italy, from June 13th to June 17th, 2016.

Short courses will be held on June 12th, 2016 at the nearby University of Cagliari.

What is Bayesian Analysis?

Scientific inquiry is an iterative process of integrating and accumulating information. Investigators assess the current state of knowledge regarding the issue of interest, gather new data to address remaining questions, and then update and refine their understanding to incorporate both new and old data. Bayesian inference provides a logical, quantitative framework for this process. It has been applied in a multitude of scientific, technological, and policy settings.

Rev Thomas Bayes"Bayesian" refers to the Reverend Thomas Bayes. The development of probability theory in the early 18th century arose to answer questions in gambling, and to underpin the new and related ideas of insurance. A problem arose, known as the question of inverse probability: the mathematicians of the time knew how to find the probability that, say, 4 people aged 50 die in a given year out of a sample of 60 if the probability of any one of them dying was known. But they did not know how to find the probability of one 50-year old dying based on the observation that 4 had died out of 60. The answer was found by Thomas Bayes, and was published in 1763 (the year after his death). Like many educated men of his time, Bayes was both a clergyman and an amateur scientist/mathematician. His solution, known as Bayes' theorem, underlies, and gave its name to, the modern Bayesian approach to the analysis of all kinds of data.  For more background on Bayesian Inference and Methods, Read on ...
