Wooldridge Source: J.D. Hamilton and L. Gang (1996), “Stock Market Volatility and the Business Cycle,” Journal of Applied Econometrics 11, 573-593. I obtained these data from the Journal of Applied Econometrics data archive at http://qed.econ.queensu.ca/jae/ Data loads lazily.

Students learning both econometrics and R may find the introduction
to both challenging. The wooldridge data package aims to lighten the task by efficiently
loading any data set found in the text with a single command. Data sets have been
compressed to a fraction of their original size. Documentation files contain page numbers,
the original source, time of publication, and notes from the author suggesting avenues for
further analysis and research. If one needs an introduction to R model syntax, a
vignette contains solutions to examples from chapters of the text.
Data sets are from the 7th edition (Wooldridge 2020, ISBN-13 978-1-337-55886-0),
and are backwards compatible with all previous versions of the text.
