question 39

Short Answer

A polynomial regression model is specified as: a. $Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X _ { i } + \beta _ { 2 } X _ { i } ^ { 2 } + \cdots + \beta _ { r } X _ { i } ^ { r } + u _ { i }$ .
b. $Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X _ { i } + \beta _ { 1 } ^ { 2 } X _ { i } + \cdots + \beta _ { 1 } ^ { r } X _ { i } + u _ { i }$ .
c. $Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X _ { i } + \beta _ { 2 } Y _ { i } ^ { 2 } + \cdots + \beta _ { r } Y _ { i } ^ { r } + u _ { i }$ .
d. $Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X _ { 1 i } + \beta _ { 2 } X _ { 2 } + \beta _ { 3 } \left( X _ { 1 i } \times X _ { 2 i } \right) + u _ { i }$ .
