parameter.plot.default: Graph of marginal posterior densities

In bairt: Bayesian Analysis of Item Response Theory Models

Description

Graph of marginal posterior densities for the item parameters (a, b or c).

Usage

## Default S3 method:
parameter.plot(mcmclist, ...)

Arguments

mcmclist	A mcmc.2pnob or mcmc.3pnob class object.
...	Further arguments.

Details

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.

Value

Graph of posterior densities of the item parameter (a, b or c).
