Difficulties with Reported Data
completeness is a real problem
- the people involved in the event knew everything we need to know, but rarely report it
reporting as “less than” or “undetectable”
- known as “censoring” data
- without decision level (DL = LC)
- many reports confuse DL with minimum detectable amount (MDA = LD)
MDA, DL, and uncertainty for each measurement method are seldom reported but are certainly available
