thresh.val.dorf: Find the optimal threshold value for Thresholded Optimal... In binGroup: Evaluation and Experimental Design for Binomial Group Testing

Description

Find the optimal threshold value for Thresholded Optimal Dorfman (TOD) testing.

Usage

 `1` ```thresh.val.dorf(p, psz, se = 1, sp = 1) ```

Arguments

 `p` a vector of each individual's probability of infection. `psz` the initial pool size. `se` the sensitivity of the diagnostic test. `sp` the specificity of the diagnostic test.

Details

This function finds the optimal threshold value for TOD testing for situations where the threshold value is not specified. See McMahan et al. (2012) for additional details on the implementation of TOD testing.

Value

The optimal threshold value for TOD testing.
