5star for album 1 star for Amazon classic bait and switch. The album cover pictured is not what you receive! after ordering I noticed it said US cover! Hey guys at the very least let your customers know EXACTLY what you are sending!! That said-the album is fantastic and most already know this but the surprise is the 7 inch EP-the live version of Accidents Will Happen and Alison are just stellar-I would have paid the album price for just the EP. Fabulous.
The IRT model underlying ASVAB scoring is the three-parameter logistic (3PL) model. The 3PL model represents the probability that an examinee at a given level of ability will respond correctly to an individual item with given characteristics. Specifically, the item characteristics represented in the 3PL model are difficulty, discrimination (i.e., how well the item discriminates among examinees of differing levels of ability), and guessing (i.e., the likelihood that a very low ability examinee would respond correctly simply by guessing).
