Abortion: Abortion Opinion Data

In vcdExtra: 'vcd' Extensions and Additions

Description

Opinions about abortion classified by gender and SES

Usage

data(Abortion)

Format

A 3-dimensional array resulting from cross-tabulating 3 variables for 1100 observations. The variable names and their levels are:

No	Name	Levels
1	Sex	"Female", "Male"
2	Status	"Lo", "Hi"
3	Support_Abortion	"Yes", "No"

Details

The combinations of Sex and Status represent four independent samples, having fixed Sex-Status marginal totals. Thus the Sex:Status association must be included in any loglinear model. Support_Abortion is a natural response variable.
