dfbetas.uRegress

Extracts dfbetas from <code>uRegress</code> objects by relying on
functionality from the <code>stats</code> package. Note that 
<code>dfbeta</code> and <code>dfbetas</code> are not the same (<code>dfbetas</code> are 
less than the <code>dfbeta</code> values by a 
scaling factor that reflects both the leverage of the observation in
 question and the residual model error).

A set of tools to streamline data analysis. Learning both R and introductory statistics at the same time can be challenging, and so we created 'rigr' to facilitate common data analysis tasks and enable learners to focus on statistical concepts. We provide easy-to-use interfaces for descriptive statistics, one- and two-sample inference, and regression analyses. 'rigr' output includes key information while omitting unnecessary details that can be confusing to beginners. Heteroscedasticity-robust ("sandwich") standard errors are returned by default, and multiple partial F-tests and tests for contrasts are easy to specify. A single regression function can fit both linear and generalized linear models, allowing students to more easily make connections between different classes of models.
