In this paper we propose tests for hypotheses regarding the parameters of the deterministictrend function of a univariate time series. The tests do not require knowledge of the form ofserial correlation in the data and they are robust to strong serial correlation. The data cancontain a unit root...

This paper presents results concerning the size and power of first generation panel unit root and stationarity tests obtained from a large scale simulation study, with in total about 290 million test statistics computed. The tests developed in the following papers are included: Levin, Lin and...
