B)regression coefficient
C)β value
D)slope

Question

Quizplus · Accepted Answer

The vertical distance from a point to the regression line represents the amount of error or discrepancy between the predicted value and the actual value. This error term is denoted as ε in the regression equation, and it is an important parameter to consider while evaluating the quality and accuracy of the regression model. The regression coefficient or β value represents the change in the dependent variable for a unit change in the independent variable, and the slope is the ratio of the change in y to the change in x (Δy/Δx) along the regression line. None of these measures represent the vertical distance from a point to the regression line, which is the error term.
