Details
Support_Abortion
is a natural response variable.
The combinations of Sex
and Status
represent four independent samples, having
fixed Sex
-Status
marginal totals.
There were 500 females and 600 males. Within the female group, 250 of low status and 250
of high status were sampled. Similarly for the males, with 300 in each of the low and high
status sub-groups.
This is an example of a product-multinomial sampling scheme.
the Sex:Status
association must be included in any loglinear model
where the goal is to determine how attitude toward abortion depends on the others.
Alternatively, a logit model for abortion support may provide a simpler analysis.
