  observed,
  replicated,
  discrepancies = list(mean = function(x) mean(x, na.rm = TRUE), sd = function(x)
    stats::sd(x, na.rm = TRUE), zero_rate = function(x) mean(x == 0, na.rm = TRUE))
)

Arguments

observed

Observed vector/data object.

replicated

List of replicated datasets, or matrix with one replicate per row.

discrepancies
