plot.mcmc_output: Trace and Density Plots for 'mcmc_output'

In bssm: Bayesian Inference of Non-Linear and Non-Gaussian State Space Models

Trace and Density Plots for mcmc_output

Description

Plots the trace and density plots of the hyperparameters theta from the MCMC run by run_mcmc.

Usage

## S3 method for class 'mcmc_output'
plot(x, ...)

Arguments

x	Object of class mcmc_output from run_mcmc.
...	Further arguments to bayesplot::mcmc_combo.

Details

For further visualization (of the states), you can extract the posterior samples with as.data.frame and as_draws methods to be used for example with the bayesplot or ggplot2 packages.

Value

The output object from bayesplot::mcmc_combo.

Note

For IS-MCMC, these plots correspond to the approximate (non-weighted) samples .

check_diagnostics for a quick diagnostics statistics of the model.

Examples

data("negbin_model")
# Note the very small number of iterations, so the plots look bad
plot(negbin_model)
