MULTIPLE REGRESSION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The model y = b 0 + b 1x1 + b 2x2 + e is a second-order regression model.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Terms in this set (28) In regression analysis, the model in the form y=Bo+B1x+e is called the. regression model. The mathematical equation relating the independent variable to the expected value of the dependent variable; that is, E(y)= Bo + B1x, is known as the. regression equation.

Detailed explanation-2: -ŷ = b0 + b1x where: b0 is a constant, b1 is the regression coefficient, x is the value of the independent variable, and ŷ is the predicted value of the dependent variable.

Detailed explanation-3: -b1 = the regression coefficient representing the change in y produced by each unit change in X1. In other words, this represents the effect of X1 on y. b2 = the regression coefficient representing the change in y produced by each unit change in X2. In other words, this represents the effect of X2 on y.
