Exam DISC-DA Practice Question 4
Study guide: Exam DISC-DA
A commercial auto file stores each vehicle's class as a four-digit integer taken from a class table, such as 2111, 3141 and 7398. A modeler plans to enter class_code in a GLM as a single numeric predictor. How should the field be classified?
- A) As continuous numeric, so one slope across the code values is appropriate
- B) As ordinal, so its levels can be coded in numeric order with equal steps
- C) As nominal categorical, so it enters as a set of levels rather than a slope
- D) As a discrete count, so it should be modelled with a count distribution
