G Consider a multiple regression model: y = 0 + 1x1 + 2x2 + . Which of the following is NOT the correct expression of the interpretation of the slope parameter 1? (a) The partial effect of x1 on y (b) The effect of x1 on y holding x2 constant (c) The Ceteris Paribus effect of x1 on y (d) All of the above are correct interpretation.

Completed Equation of Question:

Option (d): All of the above are correct interpretation.

Explanation:

In the given equation:

It would be inaccurate to state that: For every unit change in x1, y changes by units.

The correct statement would be: For every unit change in x1, y changes by units, keeping constant. This is the same as taking partial derivative or applying Ceteris Paribus effect (which means keeping all other variables equal which in this case is . Hence, the slope parameter is correctly interpreted by all options.

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.
