The Birth Weight data set consists of data collected on 189 women to identify the risk factors associated with the birth of a low birth weight baby. The data set was collected at the Baystate Medical Center in Springfield, Massachusetts. The variables included in this data set are summarized in Table 1.1.

The Body Fat data set consists of data collected on 252 adult males. The data were originally collected to build a model relating body density and percentage of body fat in adult males to several body measurement variables. These data were originally used in the article “Generalized body composition prediction equation for men using simple measurement techniques,” published in Medicine and Science in Sports and Exercise (Penrose et al., 1985). The variables included in this data set are summarized in Table 1.2. Two data sets have also been created from the Body Fat data set. These data sets have the same variables as the Body Fat data set and were formed by randomly sampling the Body Fat data set to create a training set of 189 observations called bodyfat-tr.xlsx and a validation set or 63 observations called bodyfat-val.xlsx. These data sets are used in the model validation sections of the text.

The Coronary Heart Disease data set consists of 100 observations on patients who were selected in a study on the relationship between the age and the presence of coronary heart disease. The variables included in this data set are summarized in Table 1.3.

The Prostate Cancer Study data set consists of 380 patients in a study to determine whether the variables measured at a baseline medical examination can be used to predict whether the prostatic tumor has penetrated a prostatic capsule. The data were collected by Dr. Donn Young at the Ohio State University Comprehensive Cancer Center and the data have been modified to protect subject confidentiality. Variables included in this data set are summarized in Table 1.4.

The Intensive Care Unit data set consists of 200 observations on subjects involved in a study on the survival of patients following admission to an adult intensive care unit (ICU). The data set was collected at the Baystate Medical Center in Springfield, Massachusetts, and the variables included in this data set are summarized in Table 1.5.
