drugcost

These data are to try to understand the effect of health plan characteristics
on drug costs.  Health plans vary in size, given as member months.  Some plans
use generic drugs more than others.  All differ on copayments.  Some have
strong restrictions on which drugs can be dispensed
value of RI=0 means that all drugs are dispensed, RI=100 means that only
one per category is avaiable.  The goal is to determine the terms that are
related to cost, and in particular to understand the role of GS and RI in
determining cost.

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 boot.case.
        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 boot.case. 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.
