This page refers to the current version BMS 0. Music from http The following R code models a censored dependent variable (in this case academic aptitude) using a traditional least squares, tobit, and Bayesian approaches. Bayesian model averaging has increasingly witnessed applications across an array of empirical contexts. When comparing models fitted by maximum likelihood to the same data, the smaller the AIC or BIC, the better the Bayesian analysis treats all parameters as random, assigns prior distributions to char- acterize knowledge about parameter values prior to data collection, and uses the joint posterior distribution of parameters given the data as the basis of inference.

I am on two of the lists: R-help (Main R Mailing List: Primary help) and R-sig-finance (Special Interest Group for 'R in Finance'). The RCTs used in the meta-analysis are summarized in more detail by Gøtzsche et al. In Bayesian statistics, the uncertainty about the unknown parameters is quantified using probability so that the unknown parameters are regarded as random variables. The book provides the theoretical background in an easy-to-understand approach, encouraging readers to examine the processes that generated their data. Bayesian inference is a powerful and increasingly popular statistical approach, which allows one to deal with complex problems in a conceptually simple and unified way.
