Suppose We Estimate the Regression Y_t = β₀ + β₁X_1t

question 158

Multiple Choice

Suppose we estimate the regression Y_t = β₀ + β₁X_1t + β₂X_2t + β₃X_3t + β₄X_4t + ε_t using 36 months of data.Using the residuals from this regression,we run another regression of on the predicted values
_t.From this regression we get a coefficient of determination R² of 0.09.Let H₀ be that there is no heteroscedasticity.What can you conclude?

• A)Reject H₀ at α = 0.05.
• B)Reject H₀ at α= 0.10.
• C)Reject H₀ at α = 0.01.
• D)Unable to reject H₀ at α > 0.10.
