From mls import mcmc_sample
WebThe MCMC algorithm is a deterministic function of the simple random number generator (RNG) inputs that are now exposed. Those simple RNG (uniform, normal, gamma, beta, etc.) are already well-tested (e. g., code from R core packages). Only need to verify that MCMC algorithm correctly implements the correct deterministic function of simple RNG ...
