Find the optimal pool sizes for Pool-Specific Optimal Dorfman (PSOD) testing
Find the set of optimal pool sizes for Pool-Specific Optimal Dorfman (PSOD) testing.
pool.specific.dorf(p, max.p, se, sp)
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. |
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.
