densplot {coda}R Documentation

Probability density function estimate from MCMC output


Displays a plot of the density estimate for each variable in x, calculated by the density function.


densplot(x, show.obs=TRUE, bwf, main, ylim, ...)


x An mcmc or mcmc.list object
show.obs Show observations along the x-axis
bwf Function for calculating the bandwidth. If omitted, the bandwidth is calculate by 1.06 times the minimum of the standard deviation and the interquartile range divided by 1.34 times the sample size to the negative one fifth power
main Title. See par()
ylim Limits on y axis. See par()
... Further graphical parameters


You can call this function directly, but it is more usually called by the plot.mcmc function.

If a variable is bounded below at 0, or bounded in the interval [0,1], then the data are reflected at the boundary before being passed to the density() function. This allows correct estimation of a non-zero density at the boundary.
