VariationalBayesThis may be used to plot, or save plots of, the iterated history of
the parameters and variances, and if posterior samples were taken,
density plots of parameters and monitors in an object of class
vb.
# S3 method for vb
plot(x, Data, PDF=FALSE, Parms, …)This required argument is an object of class vb.
This required argument must receive the list of data that was
supplied to VariationalBayes to create the object
of class vb.
This logical argument indicates whether or not the user wants Laplace's Demon to save the plots as a .pdf file.
This argument accepts a vector of quoted strings to be matched for
selecting parameters for plotting. This argument defaults to
NULL and selects every parameter for plotting. Each quoted
string is matched to one or more parameter names with the
grep function. For example, if the user specifies
Parms=c("eta", "tau"), and if the parameter names
are beta[1], beta[2], eta[1], eta[2], and tau, then all parameters
will be selected, because the string eta is within
beta. Since grep is used, string matching uses
regular expressions, so beware of meta-characters, though these are
acceptable: ".", "[", and "]".
Additional arguments are unused.
The plots are arranged in a \(3 \times 3\) matrix. The
purpose of the iterated history plots is to show how the value of each
parameter, variance, and the deviance changed by iteration as the
VariationalBayes attempted to maximize the logarithm
of the unnormalized joint posterior density. If the algorithm
converged, and if sir=TRUE in
VariationalBayes, then plots are produced of
selected parameters and all monitored variables.
