Data files and a few functions used in the textbook S. Weisberg (2005), 'Applied Linear Regression,' 3rd edition, Wiley are presented. This package depends on the car package. Many functions formerly in alr3 have been renamed and now reside in car. Data files have been lightly modified to make some data columns row labels. Many of these files are also in the newer alr4 package.
Changes to Version 2.0.5 o Documentation for UN3 updated. Minor changes for compatability with R 2.14.
Changes to Version 2.0.2 o A correction was made to the NAMESPACE.
Changes to Version 2.0.1 o A correction was made to the NAMESPACE.
Changes to Version 2.0.0
o 'alr3' now formally depends on 'car'. o Most functions were rewritten, and almost all have been moved to
the 'car' package with slightly different names. Old function names continue to work calling the new function in 'car'. The exception is the 'bcpower' function in the old 'alr3', which has been superceded by the new 'powerTransform' function in 'car', but with different arguments.
o All data sets remain in 'alr3'. In some cases, variable names have
become row labels rather than a variable. The 'longley' data was been removed, as it is in the 'datasets' package in base R. The 'forbes' data in the 'alr3' package has one additional column with rounded logarithms of one of the base variables, and is otherwise identical to the 'forbes' data in the MASS package.
