Question

a. multiple regression model
b. a least squares regression model
c. quadratic regression model
d. a simple regression model

Answer 1

Answer:

c

Step-by-step explanation:

Answer 2

Answer:

Option C) Quadratic regression model

Step-by-step explanation:

Quadratic regression model

• It is regression model in which states a non-linear relationship between the independent and dependent variables.
• It includes the dependent variable and the square of the independent variable.

• $\hat{y}= b_0 + b_1x + b_2x^2$

where x is the independent variable and $\hat{y}$ is the dependent variable.

• It is also referred to as second-order polynomial model.
• It is used when the data shape resembles to a parabola.

Thus, the correct answer is

Option C) Quadratic regression model
