All other things being held constant what is the change in t

All other things being held constant, what is the change in the dependent variable for eighteen unit change in the first independent variable for the multiple regression equation:

= 5.2 + 6.3X₁ - 7.1 X₂?

-114.2

+111.5

+112.3

+113.4

Solution

All other things being held constant, what is the change in the dependent variable for eighteen unit change in the first independent variable for the multiple regression equation:

= 5.2 + 6.3X₁ - 7.1 X₂?

-114.2

+111.5

+112.3

+113.4

Answer = +113.4

Note: for one unit change in x1 , the change in y is +6.3

For 18 units, 18*6.3 = +113.4
