For each sample, participants report whether almond, cashew and peanut are detected or not detected. For each positive result, participants are also asked to indicate whether the finding represents adulteration (> 1.0 %) or allergen contamination. Results and classifications are assessed against the known composition of the test items. Participants may additionally submit quantitative results. If at least five quantitative results are available for a given parameter in a sample, a statistical evaluation is also provided. This includes kernel density estimation, outlier tests, robust mean, robust standard deviation and z-scores. The assigned value is the robust mean of participants results.
