sph.binom {RSurveillance}

Binomial population specificity for imperfect test

Description

Calculates population specificity for a large or unknown population, using the Binomial distribution and adjusting for cut-point number of positives

Usage

sph.binom(n, c = 1, sp)

Arguments

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
