Redo Example 2.12 using log-linear models.

Example 2.12 Consider the association between gender and depression in the DOS. Although gender is nominal in nature, its binary representation in that study allows us to treat it as an ordinal variable so that we can apply the Q statistic to measure the direction and strength of association between gender and severity of depression. Assign scores to the row and column levels as follows: R =0, R21, C =0, C2 = 1, C3 = 3.
