Breusch-pagan test, Advanced Statistics

The Null Hypothesis - H0:  There is no heteroscedasticity i.e. β1 = 0

The Alternative Hypothesis - H1:  There is heteroscedasticity i.e. β1 0

Reject H0 if Q = ESS/2  > 2094_Tests for Heteroscedasticity.png

Regression Analysis: gt versus totexp, age, nk

 

The regression equation is

gt = 1.19 - 0.00208 totexp + 0.00002 age + 0.0111 nk

Since Q = 5.58350 < 7.81 = 2094_Tests for Heteroscedasticity.png, there is sufficient evidence to accept H0 which suggests that there is no heteroscedasticity from the Breusch-Pagan test at 5% significance level which means that one or more slopes are zero.
