ABSTRACT
This chapter considers unordered r×c $ r\times c $ tables, where r or c or both are greater than two, as well as ordered r×c $ r\times c $ tables, where both r and c are greater than two. It presents notation and sampling distributions and different odds ratios as effect measures. The chapter describes different types of odds ratios and their ability to describe the association between rows and columns in r×c $ r\times c $ tables. It analyzes the data under the assumption that the Body mass index categories were unordered. The chapter argues that for regarding the Body mass index categories as unordered in some settings and ordered in other settings, depending on the context. L. K. Lund et al. report psychiatric morbidity in young adulthood in two low birth weight groups and a control group.
