Death Rate Data

Description

Death rates per 100 in Virginia in 1940. The death rates are cross-classified by age group (rows) and population group (columns). The age groups are: 50-54, 55-59, 60-64, 65-69, 70-74 and the population groups are Rural/Male, Rural/Female, Urban/Male and Urban/Female.

This provides a rather nice 3-way analysis of variance example.

Usage

data(VADeaths)

Format

A matrix with 5 rows and 5 columns.

Examples

data(VADeaths)
n <- length(dr <- c(VADeaths))
nam <- names(VADeaths)
d.VAD <- data.frame(
 Drate = dr,
 age = rep(ordered(rownames(VADeaths)),length=n),
 gender= gl(2,5,n, labels= c("M", "F")),
 site =  gl(2,10,  labels= c("rural", "urban")))

summary(aov.VAD <- aov(Drate ~ .^2, data = d.VAD))
plot(aov.VAD)
