Calculates the effective sampling rate (esr).
# S3 method for mcmcarray
esr(x, by = "all", as_df = FALSE, na_rm = FALSE, ...)An object.
A string indicating whether to determine by "term", "parameter" or "all".
A flag indicating whether to return the results as a data frame versus a named list.
A flag specifying whether to ignore missing values.
Other arguments passed to methods.
A number between 0 and 1 indicating the esr value.
By default $$\frac{1}{1 + 2 \sum_{k = 1}^\infty\rho_k(\theta)}$$ from Brooks et al. (2011) where the infinite sum is truncated at lag \(k\) when \(\rho_{k+1}(\theta) < 0\).
