Dhruv Goel

After forming a model, use Quandt test. It will show F-values for different structural breaks. Choose the one with the highest value. However, be careful in establishing the break's relevance.

Laxmi Narayan

@Dhruv Goel, The series is stationary at 2nd difference and when I apply QLR test, it shows structural break in 2009 but when QLR test is applied on level data, it shows break in 2010. Which one is to considered as a break.

@Laxmi Sorry, for the late reply. According to me you should use the break as is shown differenced series, as that is what you are using in the model.
