Mathematics · Statistics - Regression Analysis
Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R): Assertion (A): When comparing the relative strength or importance of several predictor variables in a multiple regression model, one should compare standardized regression coefficients (β) rather than unstandardized regression coefficients (b). Reason (R): Unstandardized regression coefficients (b) are measured in the raw units of the respective variables, meaning a larger b value may simply reflect a smaller measurement scale rather than a stronger effect. Choose the correct option:
- 1Both (A) and (R) are true and (R) is the correct explanation of (A)
- 2Both (A) and (R) are true, but (R) is not the correct explanation of (A)
- 3(A) is true, but (R) is false
- 4(A) is false, but (R) is true✓
Correct answer
(A) is false, but (R) is true
