Provided here are the files for use with the text Regression with Graphics by Lawrence C. Hamilton (Pacific Grove, CA: Brooks/Cole, 1992).
There are 43 .dta datasets. You may download them in either of two formats:
We suggest that you create a new directory, such as C:\rwg, and copy the materials there.
Information on the individual datasets, including the original source, is provided below. Note that the datasets used in the book sometimes diverge from the original in that they contain only a subset of the variables or observations. Please also give credit to the original researchers if you write about or otherwise use the data.
Datasets are documented under the chapter in which they first appear.
