A General Latent Trait Model for Response Processes.

Embretson (Whitely), Susan

Psychometrika, v49 n2 p175-86 Jun 1984

The purpose of this paper is to propose a general multicomponent latent trait model (LTM) for response processes. It combines the linear logistic LTM with the multicomponent LTM. Joint maximum likelihood estimators are presented for parameters of the general multicomponent LTM and an application to cognitive test items is described. (Author/BW)
