Program:	UWerrTexp
Keywords:	Error analysis, MATLAB, autocorrelations
Authors:	F. Virotta
Short description:	Error analysis software for Markov chain Monte Carlo data. It is based on the code UWerr of U. Wolff in www.physik.hu-berlin.de/com/ALPHAsoft and implements the proposal presented in dx.doi.org/10.1016/j.nuclphysb.2010.11.020. The main feature is that a tail of the autocorrelation function due to slow modes is estimated.
