WebSep 21, 2010 · Principal component analysis on standardized residuals has been used to check dimensionality, especially under the family of Rasch models. It has been suggested that an eigenvalue greater than 1.5 for the first eigenvalue signifies a violation of unidimensionality when there are 500 persons and 30 items. WebWinstepsis one of them. Winsteps implements two methods of estimating the Rasch parameter from ordered qualitative observations: the JMLE method (Joint Maximum Likelihood Estimation) and the PROX method (Proximal operator). Winsteps' JMLE equations have been enhanced to simultaneously estimate a person's ability and item …
