In evidence: Analysis of Scientific Evidence Using Bayesian and Likelihood Methods

Description Details Author(s) References

The functions in this package include Bayesian and likelihood alternatives to the standard statistical hypothesis tests that form part of base R. Their aim is to provide a wider perspective on how statistical evidence can be analyzed than the usual hypothesis-testing one. In view of the increasing importance in science of Bayesian and likelihood inference a wider exposure to these alternatives has become overdue.

This package makes Bayesian and likelihood analyses of simple statistical problems as convenient as traditional frequentist ones are in R. In addition, it makes effective use of R's excellent plotting capabilities, and facilitates exploratory data analysis and an interactive approach to modeling. Both data exploration and model exploration are crucial in data analysis, and these are facilitated by an interactive and graphics-centered approach.
