Generates density or histogram plots for each estimated parameter from MCMC output, with annotated quantiles and optional true values if available. It helps users visualize the posterior distribution of model parameters.
Usage
post_plot(
results_list,
params_to_estimate,
dim_plot,
show_true = TRUE,
true_value = NULL,
show_prior = FALSE,
prior_n = 10000,
title = "",
run_labels = NULL,
plot_type = "histogram"
)Arguments
- results_list
A list containing MCMC results from multiple runs. Each element should contain posterior samples.
- params_to_estimate
A character vector of parameter names to include in the plot.
- dim_plot
A numeric vector of length 2 specifying the number of rows and columns for arranging plots.
- show_true
Logical; if
TRUE, true parameter values will be indicated on the plots if provided.- true_value
A named numeric vector of true values for parameters (optional). Must match
params_to_estimateif used.- show_prior
Logical; if
TRUE, prior distributions will be overlaid on the plots.- prior_n
Integer; the number of points to sample from the prior distribution.
- title
A character string specifying the title for the entire plot layout (optional).
- run_labels
A character vector specifying labels for each MCMC run (optional). Must match the length of
results_list.- plot_type
A character string specifying the type of plot:
"histogram"or"density".
