AutoPollution

<p>Measurements of noise levels for different filters to reduce pollution levels of automobiles.</p>

datasets

Datasets for the textbook Stat2: Modeling with Regression and ANOVA (second edition).
The package also includes data for the first edition, Stat2: Building Models for a World of Data
and a few functions for plotting diagnostics.
