WebR Tutorial 6. In this tutorial we’ll use the ANES data we used in Tutorial 2. Read in the file and clean it like we did in the Preliminaries section of that tutorial. The only package we haven’t used before is arm. It allows us to display OLS output more cleanly and to extract standard errors. Webconfint is a generic function. The default method assumes normality, and needs suitable coef and vcov methods to be available. The default method can be called directly for comparison with other methods. For objects of class "lm" the direct formulae based on t t values are used.
