Yang's network tomography data

Description

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).

Usage

data(YangNetwork)

Format

An object of class list of length 4.
