Q3 Part (A)

Where investment (I), government expenditure (G), and gross domestic product (Y) are measured in US$ billion and ̂u is the regression residual
Is there any problem of Hetroscedasticity in above model? How do you know?

Q3:
A researcher fitted following regression equation using data of 30 countries
а.
Î =
(7.79)
18.10
1.07G +
0.36 Y
Se =
(0.14)
(0.02)
R? = 0.99
and
û? = 10.3 + 1.2G + 0.05Y + 0.12G? + 0.03Y² + 1.5GY
R2= 0.45
Where investment (I), government expenditure (G), and gross domestic product
(Y) are measured in US$ billion and û is the regression residual
Is there any problem of Hetroscedasticity in above model? How do you know?
