From: Reappraisal of the glycerol test in patients with suspected Menière’s disease
Comparison between data and model for three groups of patients: (a) all patients, (b) the poor candidates for the glycerol test, and (c) the good candidates. Convolving the theoretical frequency distribution shown on the left with the probability density function of the measurement error yields the observed frequency distribution shown in the middle (histogram representing the MTR values obtained from the data, curve representing the model). The corresponding cumulative frequency distributions are shown on the right.
