Given the Multiple Linear Regression Equation $\hat { y } = \hat { \beta } _ { 0 } + \hat { \beta } _ { 1 } x _ { 1 } + \hat { \beta } _ { 2 } x _ { 2 } ,$

question 100

True/False

Given the multiple linear regression equation, $\hat { y } = \hat { \beta } _ { 0 } + \hat { \beta } _ { 1 } x _ { 1 } + \hat { \beta } _ { 2 } x _ { 2 } ,$ the value of $\hat { \beta } _ { 2 }$ is the estimated average increase in y for a one unit increase in x2, whilst holding x1 constant.
