title: 'xtrec: Panel Unit Root Test Based on Recursive Detrending'
version: 1.0.0
doi: 10.32614/CRAN.package.xtrec
abstract: 'Implements the recursively detrended panel unit root tests proposed by
  Westerlund (2015) <https://doi.org/10.1016/j.jeconom.2014.09.013>. Two variants
  are provided: the basic t-REC test assuming iid errors, and the robust t-RREC test
  that accounts for serial correlation, cross-sectional dependence, and heteroskedasticity
  via defactoring and BIC-selected lag augmentation. Both tests have a standard normal
  null distribution requiring no mean or variance correction. The panel must be strongly
  balanced.'
