Find the optimal pool sizes for Pool-Specific Optimal Dorfman (PSOD) testing

Description

Find the set of optimal pool sizes for Pool-Specific Optimal Dorfman (PSOD) testing.

Usage

pool.specific.dorf(p, max.p, se, sp)

Arguments

p

a vector of each individual's probability of infection.

max.p

the maximum allowable pool size.

se

the sensitivity of the diagnostic test.

sp

the specificity of the diagnostic test.

Details

This function finds the set of optimal pool sizes for PSOD testing. PSOD testing uses a greedy algorithm and does not consider all possible sets of pool sizes. See McMahan et al. (2012) for additional details on the implementation of PSOD testing.

Value

The optimal set of pool sizes for PSOD testing.
