#' Yang's network tomography data 
#'
#' Simulated traffic counts on Yang's (1995) network. The aim is to sample the corresponding origin-destination traffic volumes that are consistent with those counts.
#' The dataset appears as a list prepared for that purpose. 
#' Components of the list are A (the configuration matrix, which in this case is the link-path incidence matrix); y (observed traffic counts); lambda (assumed mean origin-destination traffic volumes); 
#' and MarkovBasis (a matrix with columns corresponding to the vectors in full Markov basis for the resampling problem).
