Software for the Application of Discrete Latent Structure Models to Item Response Data.
Edward H. Haertel · 1996
These FORTRAN programs and MATHEMATICA routines were developed in the course of a research project titled Achievement and Assessment in School Science: Modeling and Mapping Ability and Performance. Their use is described in other publications from that project, including Traits or Latent States? The Role of Discrete Models for Ability and Performance. Four FORTRAN programs (CLOSURE, DISATT, INTERSECT, and SUPERCLOSE) and one set of MATHEMATICA routines (Ability/Task Representations) are included. The use of each program is described in the comments included in the source code listings.
