As such, the e-book addresses the wishes of readers who use CTT and IRT of their paintings yet don't unavoidably have an intensive mathematical historical past. The e-book additionally sheds gentle on universal misconceptions in utilizing dimension versions, and offers an built-in method of various dimension equipment, reminiscent of contrasting CTT with IRT and multidimensional IRT versions with unidimensional IRT types. at any place attainable, comparisons among types are explicitly made. additionally, the booklet discusses suggestions for try out equating and differential merchandise functioning, in addition to Bayesian IRT versions and believable values utilizing uncomplicated examples.
