Question: 3. Given the model logit P(X) + BSSU+1AGE + 2 SEX + SSU(6AGE + 8SEX), where SSU denotes social support score and is an ordinal

3. Given the model logit P(X) + BSSU+1AGE + 2 SEX + SSU(6AGE + 8SEX), where SSU denotes "social support score" and is an ordinal variable ranging from 0 to 5, answer the following questions about the above model:

a. Give an expression for the odds ratio that compares a person who has SSU = 5 to a person who has SSU = 0, controlling for AGE and SEX.

b. Give an expression for the odds ratio that compares a person who has SSU = 1 to a person who has SSU = 0, controlling for AGE and SEX.

c. Give an expression for the odds ratio that compares a person who has SSU = 2 to a person who has SSU 1, controlling for AGE and SEX.

d. Assuming that the same data set is used for parts b and

c, what is the relationship between the odds ratios computed in parts b and c?
