Interpreting Regression Coefficients in Multiple Regression In multiple regression models, for the interpreting regression coefficients, case, the unstandardized multiple regression coefficient is interpreted as the predicted change in $Y$ (i.e., the dependent variable abbreviated as DV) given a one-unit change in $X$ (i.e., the independent variable abbreviated as IV) while …
How are the regression coefficients interpreted in simple regression? The simple regression model is The formula for Regression Coefficients in Simple Regression Models is: $$b = \frac{n\Sigma XY – \Sigma X \Sigma Y}{n \Sigma X^2 – (\Sigma X)^2}$$ $$a = \bar{Y} – b \bar{X}$$ The basic or unstandardized regression coefficient …
