BayesDB is aimed at:
Users without statistics training but who have tabular data and questions they'd like to answer.
Users with statistics expertise who either have a problem that doesn't fit the standard supervised templates (e.g. the data is too sparse) or who want to analyze a tabular dataset but don't have the time or inclination for custom modeling.
The main goal is to broaden access to analytics and increase productivity. We also hope it will increase the reliability of the empirical reasoning performed by non-experts, who currently lack the ability to build good models or critique the simplistic models that they do have access to.
