Bias In Weighted Likelihood Estimation When Using The Rasch Model, D Roberts, Ray Adams Dec 1996

Bias In Weighted Likelihood Estimation When Using The Rasch Model, D Roberts, Ray Adams

Prof Ray Adams

There are three methods of maximum likelihood estimation that are commonly used with Rasch item response models: Joint maximum likelihood, which provides point estimates for both person and item parameters; conditional maximum likelihood, which produces estimates for the item parameters only, and marginal maximum likelihood, which produces estimates of the item parameters and parameters of the distribution from which it has been assumed that the persons have been sampled. A number of approaches have been suggested for obtaining ability estimates for subsequent use in reporting or analysis when either conditional or marginal methods have been used to obtain the item …


Implications For Higher Education Of A Competency-Based Approach To Education And Training, John Bowden, Geoff Masters Dec 1992

The authors suggest that universities, the professions, employers and the community have much to gain from the activities of the past few years concerned with the development of competency-based standards by the professions, although they do not believe that a full-blown competency-based approach to education will become dominant in university courses.
