alr3 (1.1.12)

Methods and data to accompany Applied Linear Regression 3rd edition.

This library is a companion to the textbook S. Weisberg (2005), "Applied Linear Regression," 3rd edition, Wiley. It includes all the data sets discussed in the book (except one), and several few functions that are tailored to the methods discussed in the book. Ver. 1.0.3 corrects bugs in (1) weights for POD models; (2) use of 'subset' arguments with Ver. 1.0.4 corrects a few bugs with overparameterized models. Ver. 1.0.5 changes one default argument. Ver 1.0.6 replaces the pure.error.anova function so it prints nicer and works with interactions. Ver 1.0.7 fixes a bug in residual.plots and adds an additional argument and adds a new function alrweb to access the website for the book in a browser. Ver 1.0.8 fixed a bug in delta.method for generalized linear models. Ver 1.0.9 fixes a bug with Yeo Johnson transformations. Ver 1.1.0 drops the conf.intervals function in favor of the confint function in stat, includes several minor bug fixes, and makes the package fully compatible with version 2.6.0 of R. 1.1.2 corrects a bug introduced in Version 1.1.7 adds a namespace. Ver 1.1.8 fixes more bugs. Ver. 1.1.9 updated the delta.method to work with a user-supplied estimate of the variance matrix. 1.1.10 removed a conflict with another package. Data files lightly modified to make some data columns row labels.
