esr.mcarray: Effective Sampling Rate

In mcmcr: Manipulate MCMC Samples

Description

Calculates the effective sampling rate (esr).

Usage

## S3 method for class 'mcarray'
esr(x, by = "all", as_df = FALSE, na_rm = FALSE, ...)

Arguments

x	An object.
by	A string indicating whether to determine by "term", "parameter" or "all".
as_df	A flag indicating whether to return the results as a data frame versus a named list.
na_rm	A flag specifying whether to ignore missing values.
...	Other arguments passed to methods.

Details

By default

\frac{1}{1 + 2 ∑_{k = 1}^∞ρ_k(θ)}

from Brooks et al. (2011) where the infinite sum is truncated at lag k when ρ_{k+1}(θ) < 0.

Value

A number between 0 and 1 indicating the esr value.
