How can I get a combination of contingency tables and chi

The way to do this is to estimate the appropriate model on the full contingency table (including the structural zeros) and then subtract the sum of the chi-square values associated with the zero cells from the total chi-square test. This generates a reduced chi-square test of independence only for the reduced contingency table.
