heart: Heart Attack Data
In glm2: Fitting Generalized Linear Models

Description Usage Format Details References

This data set is a cross-tabulation of data on 16949 individuals who experienced a heart attack (ASSENT-2 Investigators, 1999). There are 4 categorical factors each at 3 levels, together with the number of patients and the number of deaths for each observed combination of the factors. This data set is useful for illustrating the convergence properties of glm and glm2.

1	data(heart)

A data frame with 74 observations on the following 6 variables.

Deaths: number of deaths
Patients: number of patients
AgeGroup: categorization of the age of the patients
Severity: severity of the heart attack
Delay: categorization of the time from heart attack to treatment
Region: geographical region in which the patients were treated

The variable AgeGroup groups the age of the patients as follows: 1 = <65 years, 2 = 65-75 years, 3 = >75 years. The variable Delay groups the time from heart attack onset to treatment as follows: 1 = <2 hours, 2 = 2-4 hours, 3 = >4 hours. The variable Severity denotes the severity of the heart attack using the Killip class: 1 = least severe (class I), 2 = middle severity (class II), 3 = most severe (class III or IV). The variable Region provides the geographical region in which the patients were treated: 1 = Western countries, 2 = Latin America, 3 = Eastern Europe. This data set is useful for illustrating the convergence properties of glm and glm2; see examples in the help documentation for glm2.
