n.pooled: Sample size for pooled testing for freedom

In evansergeant/RSurveillance: Design and Analysis of Disease Surveillance Activities

Description

Calculates sample size to achieve desired population-level sensitivity, assuming pooled sampling and allowing for imperfect sensitivity and specificity of the pooled test

Usage

n.pooled(sep, k, pstar, pse, psp = 1)

Arguments

sep	desired population sensitivity (scalar or vector)
k	pool size (constant across pools) (scalar or vector of same length as sep)
pstar	design prevalence (scalar or vector of same length as sep)
pse	pool-level sensitivity (scalar or vector of same length as sep)
psp	pool-level specificity (scalar or vector of same length as sep)

Value

vector of sample sizes

Examples
