URCOVAR: Stata module to perform Elliott-Jansson test for unit roots with stationary covariates
urcovar performs the test for a unit root in depvar in the context of one or more stationary covariates (listed in varlist) which was proposed by Elliott and Jansson (J. Econometrics, 2003) as a generalization of the CADF test of Hansen (Econometric Thy., 1995). The Elliott-Jansson test constructs a VAR in the model of the stationary covariates and the quasi-difference of depvar. As in the Dickey-Fuller (dfuller) or Elliott-Rothenberg-Stock DF-GLS (dfgls) unit root tests, the model can include no deterministic terms, constants or constants and time trends.
