The person-fit analysis is a technique for determining if a person's results on a given test are valid, meaning they are a result of the trait being tested, and not some external factor such as cheating, falling asleep in the middle of the test or otherwise. An item-score vector is a list of "scores" that a person gets on the items of a test, where "1" is correct and "0" is incorrect.
