plot_posterior_parameters: Plot parameter posterior distributions

Description

Plotting posterior distributions (and optionally prior distributions) from ABC results.

Usage

plot_posterior_parameters(data, ...)
# S3 method for abc
plot_posterior_parameters(data, abc_input = NULL, ...)

Value

Invisibly returns `NULL`. Called for its side effect of producing plots.

Arguments

data

An abc object containing posterior samples in adj.values or unadj.values.

...

Additional arguments:

n_rows

Integer; number of rows in the plot grid (default: 2)

n_cols

Integer; number of columns in the plot grid (default: 2)

interactive

Logical; whether to pause between pages and wait for input

abc_input

Optional abc_input object containing prior samples for comparison. If provided, prior distributions are shown as red histograms and posterior distributions as blue density curves.

Details

The plots use the following visual encoding:

• Posterior distributions: blue density curves

• Prior distributions (if provided): red histograms with transparency

Examples

# Load ABC output from saved file
abc_file <- system.file(
  "extdata", "rdm_minimal", "abc", "abc_rejection_model.rds",
  package = "eam"
)
abc_rejection_model <- readRDS(abc_file)

# Load ABC input for prior comparison
abc_input_file <- system.file(
  "extdata", "rdm_minimal", "abc", "abc_input.rds",
  package = "eam"
)
abc_input <- readRDS(abc_input_file)

# Plot posterior distributions with prior comparison
plot_posterior_parameters(abc_rejection_model, abc_input)
