Plot MCMC Trace

Creates trace plots for MCMC chain convergence assessment.

Usage

plot_mcmc_trace(
  fit,
  parameters = NULL,
  chains = NULL,
  title = "MCMC Trace Plots",
  alpha = 0.8
)

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.

chains

Integer vector of chain numbers to plot. If NULL, plots all chains.

title

Plot title

alpha

Numeric. Transparency for chain lines

Value

A ClinicalPlot object

Examples

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

# Plot trace for specific parameter
plot <- plot_mcmc_trace(fit, parameters = "b_Intercept")

# Plot specific chains
plot <- plot_mcmc_trace(fit, chains = 1:2)
} # }
