The matching distance metric is used when comparing observations with binary responses. Suppose a survey firm has surveyed its clients and collected information on five binary (0 for "no" and 1 for "yes") categorical variables:
1. Has a Masters degree (whether client has master's degree or beyond)
2. Married (whether client is married)
3. Family (whether client has dependent children)
4. Mortgage (whether client has a mortgage on a home)
5. Age (whether client's age is greater than 50)
Consider clients with observations: u=(1,1,0,0,1) and v=(0,1,0,1,0).
Calculate the matching distance between the two clients. (Round your answer to two decimal places)
