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 1.

Spatial Pattern Analyses to Detect Rare Disease Clusters

Lance A. Waller, Bruce W. Turnbull, Larry C. Clark, and Philip Nasca

The file ch1a.dat is the case data file. It contains the following variables. There are no missing values.

ID: Integer, 10 character long identification number for a "cell" or census district in the study area.

x: Real, range (-60.85, 54.13), x-coordinate of the geographic centroid of each cell.

y: Real, range (-78.64, 58.30), y-coordinate of the geographic centroid of each cell.

pop: Integer, range (3, 12221), 1980 U.S. Census population count for each cell.

cases: Real, range (0, 9.29), incident cases of leukemia (all types) occurring between 1978 and 1982 in each cell. Fractional values can occur due to partially missing data (see text).

Note: The authors give permission to use the data freely for noncommercial purposes.
