In a study of patient confidentiality, a large number of pediatricians was surveyed. Each pediatrician was given a "fable" about a female patient less than 18 years old. There were sixteen different fables, the combinations of the factors complaint (C: 1-drug problem, 2-venereal disease), age (A: 1-14 years, 2-17 years), the length of time the pediatrician had known the family (L: 1-less than 1 year, 2-more than 5 years), and the maturity of patient (M: 1-immature for age, 2-mature for age). The response at each combination of factor levels is the fraction of doctors who would keep confidentiality and not inform the patient's parents (data modeled on Moses 1987). Analyze these data to determine which factors influence the pediatrician's decision.
