EViews.com

I want to use
-Narayan and Popp (2010) unit root test with two endogenous breaks.
-LM unit root test of Lee and Strazicich (2003) which can accommodate two breaks in the intercept and the slope.
-KPSS stationarity test of Carrion-i-Silvestre and Sansó (2007) with two endogenous breaks in the intercept and trend.

Also, I want to use
-Panel Kwiatkowski–Phillips–Schmidt–Shin (KPSS) stationarity test with multiple breaks (Carrion-i-Silvestre, Barrio-Castro, and Lopez-Bazo 2005).
- LM unit root test with structural breaks (Im, Lee, and Tieslau 2005).

Please let me know how to use these tests in Eviews.

None of the above tests are supported as in-built features. I will put them on the list for future development consideration.

Hello,

Could I please ask if in the unit root test I need to compare the estimated t-stat with all the critical values provided?
For example, in the results below do I consider my series as having a unit root at 1% and thus I need to test the first differences or as stationary (not having a unit root at 10%)? although I ve searched the forum for answers I couldnt find something relevant, so apologies if a post has skipped.


Lee Strazicich LM unit root test

Thank you very much
