plot.confint: Plot Bayesian Confidence Intervals

In BAS: Bayesian Variable Selection and Model Averaging using Bayesian Adaptive Sampling

Plot Bayesian Confidence Intervals

Description

Function takes the the output of functions that return credible intervals from BAS objects, and creates a plot of the posterior mean with segments representing the credible interval. of what the function does. ~~

Usage

## S3 method for class 'confint.bas'
plot(x, horizontal = FALSE, ...)

Arguments

x	the output from confint.coef.bas or confint.pred.bas containing credible intervals and estimates.
horizontal	orientation of the plot
...	optional graphical arguments to pass on to plot

Details

This function takes the HPD intervals or credible intervals created by confint.coef.bas or confint.pred.bas from BAS objects, and creates a plot of the posterior mean with segments representing the credible interval. BAS tries to return HPD intervals, and under model averaging these may not be symmetric. the description above ~~

Value

A plot of the credible intervals.
