Hola! I am about to do this years buying for our library, and could need help with some references.
Some people here will start to work with IRT and Rasch models. >From the book descriptions on Amazon it is difficult to decide what books to buy. I want one introductory book on IRT/Rasch, and one more profound, with sufficient detail to actually start coding. Anybody knows some good books satisfying this criteria?
