Plot MCMC Density

Creates density plots for posterior distributions.

Usage

plot_mcmc_density(
  fit,
  parameters = NULL,
  title = "MCMC Posterior Densities",
  alpha = 0.7,
  fill_colors = c("#1f77b4", "#ff7f0e", "#2ca02c", "#d62728")
)

Arguments

fit

A brmsfit object from brms package

parameters

Character vector of parameter names to plot. If NULL, selects parameters starting with "b_", or the first 5 parameters if no "b_" parameters exist.

title

Plot title

alpha

Numeric. Transparency for density areas

fill_colors

Character vector of colors for different chains

Value

A ClinicalPlot object

Examples

if (FALSE) { # \dontrun{
# Plot density for all parameters
plot <- plot_mcmc_density(fit)

# Plot density for specific parameter
plot <- plot_mcmc_density(fit, parameters = "b_Intercept")
} # }
