WebMatrix of MCMC samples. target: Target number of samples (default = 5000). Only applicable if auto=TRUE. burnin.ratio: Fraction of samples to burn-in; i.e. 2 means to remove first 1/2 of samples, 3 means 1/3, etc. (default = 2). Only applicable if auto=TRUE. auto: Whether or not to perform automatic burnin and thin based on target number of ... Webthin Scalar, positive integer representing the thinning in the MCMC burnin Scalar, non-negative integer representing the burn-in of the MCMC print_freq Scalar, positive integer representing the frequency of printing the sampled values Details In the MCMC, a componentwise Metropolis-Hastings algorithm is used.

Webnumber of MCMC samples to draw per chain (after any warm-up, but before thinning) thin: MCMC thinning rate; every thin samples is retained, the rest are discarded. warmup: number of samples to spend warming up the mcmc sampler (moving chains toward the highest density area and tuning sampler hyperparameters). WebMatrix of MCMC samples. target: Target number of samples (default = 5000).
