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 10.

Habitat Association Studies of the Northern Spotted Owl, Field Grouse, and Flammulated Owl

Fred L. Ramsey, Marti McCracken, John A. Crawford, Martin S. Drut, William J. Ripple

The file ch10.dat contains eight variables, with 30 cases for each. Each case refers to a site in the forest. The first variable, 'random', is a character variable indicating whether the site is a spotted owl nest site (=N) or a site selected at random coordinates (=R). Variables 2-8 contain the percents of mature forest (>80 years of age). The variable names indicate the outer radii of the rings in which the percents were calculated. They are: 0.91km, 1.18km, 1.40km, 1.60km, 1.77km, 2.41km, and 3.38km. So, for example, the variable '1.18km' contains the percents of mature forest in rings with outer radius 1.18km and inner radius .91km centered at the different sites.
