Frequency of qPCR replicate response within the observed data set (red dots), with boxplots representing the simulated median, IQR and whiskers at quartile + /− 1.5 IQR for the 100 repeats of simulated data, based on the modelled individual site occupancy and probabilities for both Stage 1 and Stage 2 true and false positives from the goodness of fit analysis.
