B)Y_i = ?₀ + ?₁X_i + ? $\begin{array} { l } 2 \ 1 \end{array}$ X_i+ ??? + ? $\begin{array} { l } r \ 1 \end{array}$ X_i + u_i. C)Y_i = ?₀ + ?₁X_i + ?₂Y $\begin{array} { l } 2 \ i \end{array}$ + ??? + ?_rY $\begin{array} { l } r \ i \end{array}$ + u_i. D)Y_i = ?₀ + ?₁X₁_i + ?₂X₂+ ?₃ (X₁_i × X₂_i)+ u_i.

Question

Quizplus · Accepted Answer

A polynomial regression model correctly represents the relationship between a dependent variable and one or more independent variables to a certain degree (power). The correct specification includes a constant term, coefficients for each term of the independent variable raised to some power (indicating the degree of the polynomial), and an error term.
