              CASE STUDIES IN BIOMETRY

You have obtained all of the data used by all of the authors in the twenty-one chapters of Case Studies in Biometry.

Each chapter contains either one or two data sets, except for Chapter 19, which has seven data sets. Corresponding to each data set are ASCII files with extensions ".dat" (the data), ".txt" (the data description file), and ".sas" (a simple SAS program to read the .dat file).

For chapters containing only one data set, the file name prefix is "ch" followed by chapter number, and then the above extensions. For instance, for Chapter 2 you will find files "ch2.dat", "ch2.txt", and "ch2.sas".

For chapters containing two data sets, the letters "a" and "b" are added after the chapter number. For instance, for Chapter 1, you will find the files "ch1a.dat", "ch1a.txt", "ch1a.sas", "ch1b.dat", "ch1b.txt", "ch1b.sas".

For chapter 19, there are seven data sets, ch19a.dat through ch19g.dat. Each one has the same format, but refers to different subsets of the whole data set. Details are given in the single text file, ch19.txt.

Please note permissions and usage information included in the .txt file for each subset.

CASE STUDIES IN BIOMETRY: Chapter 19.

Patterns of Lung Cancer Risk in Ex-Smokers

Brenda W. Gillespie, Michael T. Halpern, Kenneth E. Warner

The files ch19a.dat through ch19g.dat contain various subsets of the data used in this chapter. Due to the very large size of the full data set, the data were broken into these subsets to facilitate easier access by the readers.

The seven data sets and their sizes are as follows:

ch19a.dat 0.04 megs never-smokers ch19b.dat 0.67 megs current smokers: male ch19c.dat 0.61 megs current smokers: female ch19d.dat 1.15 megs former smokers: male, no college ch19e.dat 1.49 megs former smokers: male, some college ch19f.dat 0.70 megs former smokers: female, no college ch19g.dat 0.93 megs former smokers: female, some college

Total size: 5.42 megs

The ten variables listed in each file are:

Age: Age on January 1, 1982. Gender: 0=Male, 1=Female Education: 0=no college, 1=some college
Smoker: 1=never, 2=former, 3=current
Cigarettes/day: values rounded UP to the nearest 5. Years smoked: Number of years smoked as of January 1, 1982. Years quit: Number of years since smoking cessation, as of January 1, 1982 (zero indicates less than one year) Followup Time: Years from January 1, 1982 until death or last interview. Death codes: 0=alive, 1=death from other causes, 2=lung cancer death. Freq: the frequency at which each combination of variables occured.
