                  Data Diskette for
              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 7.

Survival Analysis for Size Regulation of Atlantic Halibut

Stephen J. Smith, Ken G. Waiwood, John D.Neilson

The file ch7.dat contains the following variables:

No - observation number (1,...,294). TIME - survival time of halibut (time until death) in hours. (NOTE the Table 1 in the book claims survival time is in minutes, but HOURS is the correct unit) CENSOR - censoring indicator. 1=uncensored observation; 0=censored observation. TOWD - duration (in minutes) of time trawl net was towed on the bottom. DELDEPTH - difference between maximum and minimum depth observed during tow (depth measured in meters). LENGTH - fork length of halibut in centimeters. HANDTIME - handling time (in minutes) between net coming on board vessel and fish being placed in holding tanks. LOGCAT - natural logarithm of total catch of fish in tow.
