Random Walks in the Intersection of Hyperplanes and the N-Simplex.


Consider the intersection of two spaces: the complete solution space to Ax = b and the N-simplex. The intersection of these two spaces is a non-negative convex polytope. The package walkr samples from this intersection using two Monte-Carlo Markov Chain (MCMC) methods: hit-and-run and Dikin walk. walkr also provide tools to examine sample quality. The package implements Dikin walk specified in Sachdeva (2016) .
