sph.hp {RSurveillance}

Hypergeometric population specificity calculation

Description

Calculates population specificity for a finite population and imperfect test, using Hypergeometric distribution

Usage

sph.hp(N, n, c = 1, sp)

Arguments

N

population size (scalar or vector of same length as n)

n

sample size (scalar or vector)

c

The cut-point number of positives to classify a cluster as positive, default=1, if positives < c result is negative, >= c is positive (scalar or vector of same length as n)

sp

test unit specificity (scalar or vector of same length as n)

Value

a vector of population-level specificities
