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 hgh 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.
