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 4.

Measurement Error Models for Gypsy Moth Studies

John P. Buonaccorsi

The file ch4b.dat contains the defoliation data, with the following variables:

1. mdef = mean defoliation value obtained from 20 subplot values.

2. sedef = estimated standard error of mean defoliation obtained from 20 subplot values.

3. megg = mean estimated egg mass density obtained over 20 subplots

4. seegg = estimated standard error or mean egg mass density obtained from 20 subplot values.

5. cdefegg = estimated covariance of mean defoliation and mean egg mass density obtained from 20 subplot values.

Sandy Liebhold has provided this data and given permission for its use in Case Studies in Biometry.
