ggs_density

Density plots with the parameter distribution. For multiple chains, use colours to differentiate the distributions.

Tools for assessing and diagnosing convergence of
Markov Chain Monte Carlo simulations, as well as for graphically display
results from full MCMC analysis. The package also facilitates the graphical
interpretation of models by providing flexible functions to plot the
results against observed variables, and functions to work with
hierarchical/multilevel batches of parameters
(Fernández-i-Marín, 2016 <doi:10.18637/jss.v070.i09>).

ggs_density function

<dl><dt>D</dt>
<dd>Data frame whith the simulations.</dd>
<dt>family</dt>
<dd>Name of the family of parameters to plot, as given by a character vector or a regular expression. A family of parameters is considered to be any group of parameters with the same name but different numerical value between square brackets (as beta[1], beta[2], etc).</dd>
<dt>rug</dt>
<dd>Logical indicating whether a rug must be added to the plot. It is FALSE by default, since in large chains it may use lot of resources and it is not central to the plot.</dd>
<dt>hpd</dt>
<dd>Logical indicating whether HPD intervals (using the defaults from ci()) must be added to the plot. It is FALSE by default.</dd>
<dt>greek</dt>
<dd>Logical value indicating whether parameter labels have to be parsed to get Greek letters. Defaults to false.</dd></dl>
