The appointments in this dataset were all on weekdays only (Monday - Friday). Wednesday is the most popular day for appointments (24% of all 5,000 appointments were on a Wednesday), and Friday is the least popular day (18% of all 5,000 appointments were on a Friday). The following table shows the results from a logistic regression model relating the likelihood of missing an appointment to the day of the week the appointment is schedule. Results are displayed on both the regression scale (intercept and slope) scale and the exponentiated (odds and odds ratio) scale.
