q94)The data presented in problems #1 and #2 are analyzed using multiple logistic regression analysis and the models are shown below. In the models below, the data are coded as follows: p = the proportion of children with a diagnosis of ADHD, Child Exposed and Father's Diagnosis are coded as 1=yes and 0=no.

(1) = -2.216 + 1.480 Child Exposed

(2) Father with Diagnosis: = -1.665 + 1.297 Child Exposed

(3) Father Without Diagnosis: = -2.343 + 0.823 Child Exposed

(4) = -2.398 + 1.056 Child Exposed + 0.906 Father's Diagnosis

a) Which model produces the unadjusted odds ratio? Compute the unadjusted odds ratio using the regression coefficient from appropriate model.

b) Which model produces the odds ratio in father's without a diagnosis of ADHD. Compute the unadjusted odds ratio using the regression coefficient from appropriate model.

c) What is the odds ratio adjusted for father's diagnosis?
