Area of Science:

  • Educational Measurement
  • Psychometrics
  • Statistical Modeling

Background:

  • The Rasch measurement model is a fundamental tool in psychometrics.
  • Hierarchical linear modeling (HLM) offers advanced analytical capabilities for complex data structures.
  • Implementing these models across different software requires clear guidance.

Purpose of the Study:

  • To provide a comprehensive overview of Rasch model parameterizations.
  • To demonstrate the application of five HLM software packages (SAS, MLWIN, S-PLUS, R, HLM) using a heuristic dataset.
  • To offer practical guidance for researchers on data setup, program execution, and output interpretation.

Main Methods:

  • Overview of Rasch model parameterizations.
  • Demonstration of HLM software (SAS, MLWIN, S-PLUS, R, HLM) with a heuristic dataset.
