Graph of marginal posterior densities of the item parameter a, b for mcmc.2pnob object or a, b, c for mcmc.3pnob object. The center of error bar corresponds to the marginal posterior mean and the extremes correspond to percentiles of the marginal posterior density (These are delimited by prob). For example, prob = c(0.05, 0.95) is equivalent to the 5th and 95th percentiles of the marginal posterior density.
Graph of posterior densities of the item parameter (a, b or c).
