Study guide: Exam MAS-I
In a study 100 subjects were asked to choose one of three election candidates (A, B or C). The subjects were organized into four age categories: (18-30, 31-45, 45-61, 61+).
A logistic regression was fitted to the subject responses to predict their preferred candidate, with age group (18-30) and Candidate A as the reference categories.
For age group (18-30), the log-odds for preference of Candidate B and Candidate C were -0.535 and -1.489 respectively.
Calculate the modeled probability of someone from age group (18-30) preferring Candidate B.
