Calculate Effective Sample Size

Calculates the effective sample size (ESS) for MCMC parameters.

Usage

calculate_effective_sample_size(fit)

Arguments

fit

A brmsfit object from brms package

Value

Named numeric vector of ESS values for each parameter

Details

ESS represents the number of independent samples that would give the same precision as the correlated MCMC samples. Higher values indicate better mixing of the chains.

Examples

if (FALSE) { # \dontrun{
ess_values <- calculate_effective_sample_size(fit)
print(ess_values)
} # }
