Abortion Opinion Data
Opinions about abortion classified by gender and SES
data(Abortion)
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"
|
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.
