Evaluation of Statistical Treatment of Left-Censored Contamination Data: Example Involving Deoxynivalenol Occurrence in Pasta and Pasta Substitute Products

open access: yesToxins, 2023
The handling of data on food contamination frequently represents a challenge because these are often left-censored, being composed of both positive and non-detected values.

TAMING UNCERTAINTY: THE LIMITS TO QUANTIFICATION [PDF]

open access: yesASTIN Bulletin, 2016
Taming the beast of uncertainty has been the grand project to which actuaries have dedicated much of their energy and skill over at least the last 50 years – roughly the time since, in Hans Bühlmann's (1989) famous term, “Actuaries of the Second Kind” emerged.
