Counting uncertainty and detection limits for a population frequency

The uncertainty a frequency carries from the number of events behind it, independent of where the thresholds were placed. Returned in percentage points so it combines directly with the gate placement uncertainty.

Usage

counting_uncertainty(k, n, z = 1, lod_events = 20L, loq_events = 50L)

Arguments

k

events in the population; may be a vector

n

events in the parent gate the population is expressed against; scalar or the same length as k

z

coverage factor for the Wilson half-width. The default of 1 gives a standard uncertainty, matching the convention used for the gate terms

lod_events

events below which a population is not called detected

loq_events

events below which a population is detected but not quantified

Value

a data.frame with one row per element of k, carrying the counts, the standard uncertainty, both limits expressed as percentages of the parent gate, and a verdict
