Logistic regression of detection probability. Logistic regression of a) (solid line) p(positive) vs. concentration C with false negative at log10(C) omitted; b) (dashed line) p(positive) vs. log10(C) with false negative included. Solid points show fraction of positives at each concentration with the false negative omitted; the open circle shows the calculated fraction at log10(C) with the false negative included. The apparent lower limit to the solid curve is an artefact of plotting on the log10 axis.
