Multiple Choice

An estimated multiple regression model has the form $\hat { y } = \hat { \beta } _ { 0 } + \hat { \beta } _ { 1 } x _ { 1 } + \hat { \beta } _ { 2 } x _ { 2 } .$ Which of the following best describes $\hat { \beta } _ { 2 }$ ?

• A)We estimate for each one unit increase in x2, that y will increase by \(\hat { \beta } _ { 2 }\) units, on average.
• B)Whilst holding x1 constant, we estimate for each one unit increase in x2, that y will increase by \(\hat { \beta } _ { 2 }\) units, on average.
• C)Whilst holding x2 constant, we estimate for each one unit increase in x1, that y will increase by \(\hat { \beta } _ { 2 }\) units, on average
• D)Whilst holding x1 constant, we estimate for each one unit increase in x2, that y will increase by \(\hat { \beta } _ { 2 }\) units, on average .
