Various Plots Pertaining to Mixture Model Output Using MCMC Methods
plot.MCMC.RdTakes an object of class mixMCMC and returns various graphical output for select mixture models.
Usage
# S3 method for class 'mixMCMC'
plot(x, trace.plots = TRUE,
summary.plots = FALSE, burnin = 2000, ...)Arguments
- x
An object of class
mixMCMC.- trace.plots
If TRUE, trace plots of the various parameters estimated by the MCMC methods is given.
- summary.plots
Graphics pertaining to certain mixture models. The details are given below.
- burnin
The values 1 to
burninare dropped when producing the plots insummary.plots.- ...
Graphical parameters passed to
regcrfunction.
Value
plot.mixMCMC returns trace plots of the various parameters estimated by the MCMC methods for all objects of class
mixMCMC. In addition, other plots may be produced for the following k-component mixture model functions:
- regmixMH
Credible bands for the regression lines in a mixture of linear regressions. See
regcrfor more details.
Examples
