Exam DISC-DA Practice Question 207
Study guide: Exam DISC-DA
A nearest-neighbor model for auto physical damage describes each policy by driver age (years) and vehicle value (dollars). A new policy has driver age 40 and vehicle value $30,000. Three training records are:
| Record | Driver age | Vehicle value |
|---|---|---|
| R1 | 42 | 40,000 |
| R2 | 60 | 31,000 |
| R3 | 35 | 36,000 |
In the training data, driver age has a standard deviation of 10 years and vehicle value $8,000. Which record is the nearest neighbor by Euclidean distance, on raw values and on standardized values?
- A) R2 on both raw and standardized values
- B) R2 on raw values and R1 on standardized values
- C) R2 on raw values and R3 on standardized values
- D) R3 on both raw and standardized values
