Caterpillars

<p>Measurements on a sample of Manduca Sexta caterpillars</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.
