  2. It is calculated by analyzing all possible simple univariate co-efficients based on the data set.
  3. Effects of other predictor variables are partialled out from a specific predictor variable while calculating its regression co-efficient.

Show answer and explanation

Correct answer: (C) Effects of other predictor variables are partialled out from a specific predictor variable while calculating its regression co-efficient.; (D) Both standardized and unstandardized co-efficients can be calculated.

Explanation

In multiple regression each coefficient shows the effect of one predictor with the other predictors held constant, that is, partialled out (C). Both the unstandardised (b) and the standardised (beta) coefficients can be computed (D). It is not built by simply combining separate bivariate or univariate regressions.
