Please can anyone clarify the hypothesis of a general nonlinear unit root test?

14 December 2022 0 7K Report

Please can anyone clarify the hypothesis of a general nonlinear unit root test? I have read some documents and they are really confusing. I am particularly interested in explaining the results of the Carlos & Ordonez (2014) nonlinear unit root test. I'd be grateful if relevant explanatory documents could be shared as well. Thank you.
