सांख्यिकी विश्लेषण में, समाश्रयण (रिग्रेशन) विश्लेषण मुख्य रूप से किसका माप है?

Which of the following statements are true in relation to regression coefficients? a) Both the regression coefficients will have the same sign. b) One regression coefficient may be positive and the other negative. c) One of the regression coefficients must be less than 1 if the other is greater than 1. d) Both the regression coefficients may be greater than 1.

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:
