Bootstrap resample ABC posterior samples

Usage

abc_posterior_bootstrap(abc_result, n_samples, replace = TRUE)

Arguments

abc_result: An abc object from abc
n_samples: Number of bootstrap samples to draw (default 1000)
replace: Logical, whether to sample with replacement (default TRUE)

Value

Data frame of bootstrapped parameter values

Examples

# Load an example abc output, you should generate it by applying ABC to your data
# check abc::abc for details on fitting ABC models
rdm_minimal_example <- system.file("extdata", "rdm_minimal", package = "eam")
abc_model <- readRDS(file.path(rdm_minimal_example, "abc", "abc_neuralnet_model.rds"))

# Bootstrap resample posterior parameters
posterior_params <- abc_posterior_bootstrap(
  abc_model,
  n_samples = 100
)
