What accounts for that remaining 2‰ of uncertainty?
- air7 7y agoGood question. I'd also assume that re-identification chances would always be of the form 100/k (k being the integer number of people who fit the bill)
- bsanr2 7y agoPerhaps the risk that some of the data the probability is based on is wrong, e.g., "She fits the bill except they only have 4 children and the 5th is an entry error, so it's not her."
- Cynddl 7y agoCo-author here. We designed a statistical model, which is never 100% sure a re-identification is correct. There is, e.g., a non-null probability that two individuals in the US share 5, 10, or even 15 demographics attribute.
