The Cochran's and Mantel-Haenszel statistics test the
independence of
Newspaper subscription and
response,
controlling for Income category. They
report a significant relationship, with asymptotic
significances less than 0.05.
The Breslow-Day and Tarone's statistics test the
homogeneity of the odds ratio across categories of the
layer variable.
The null hypothesis for these tests assumes that the
odds ratio for Newspaper subscription by
Response is
equivalent for each value of Income category.
The significance values are greater than 0.10, indicating that the odds
ratio is in fact homogenous, which means that you
should not use Income category to further target the
mailings.
