Some New and Some Old Results for the Polytomous Rasch Model

摘要: In the first part, polytomous Rasch model is discussed as it was presented by at Berkeley Symposium in 1960, and published Proceedings from 1961. I shall then discuss what achieved next 10 to 15 years regards estimation check of model. As Georg himself never learned program a computer, this work carried out handful or so statisticians, who worked on much done many directions. But skip period. second present quite recent result for estimates model, which extremely simple require only very few elementary combinations quantities already computed. addition solves problem identifying significant points graphs suggested Rasch.
