BILOG-MG
by Michele Zimowski, Eiji Muraki, Robert Mislevy & Darrell Bock
  • Graphical user interface
  • Efficient analysis of binary items including multiple choice or short-answer items scored right, wrong, omitted, or not-presented
  • Capable of large scale production analysis, and handling of multiple groups
  • Performs item analysis and scoring of any number of subtests or subscales
  • Non-equivalent groups equating
  • Vertical equating of test forms
  • Differential item functioning (DIF)
  • Detection and correction for parameter trends over time (DRIFT)
  • Calibration and Scoring of tests in two-stage testing procedures
  • Estimation of latent ability or proficiency distributions
  • Provision for items inserted in tests to estimate item statistics, but not included in calculation of examinee scores ("variant items")
  • Item fit statistics, theoretical and empirical reliability
  • Information curves and reliabilities for putative test forms
  • Presentation quality IRT graphics, can be imported in Word, Access, etc.
  • Detailed online HELP documentation includes description of interface, syntax, and examples.
MULTILOG
by David Thissen, Wen-Hung Chen & Darrell Bock
  • Easy to use graphical user interface
  • One, two and three-parameter logistic models
  • Samejima's model for graded responses
  • Bock's model for nominal (non-ordered) responses
  • Steinberg's model for multiple-choice items
  • Handling of multiple-alternative items, such as multiple-choice tests or Likert-type attitude questionnaires
  • Scoring of items with multiple alternatives
  • Differential item functioning (DIF)
  • Handling of data from several populations simultaneously
  • Analysis of mixtures of items types
  • Testing of item parameters across groups
  • Handling of equality constraints and fixed parameters
  • Presentation quality IRT graphics, can be imported in Word, Access, etc.
  • Detailed online HELP documentation includes description of interface, syntax, and examples.
PARSCALE
by Eiji Muraki & Darrell Bock
  • The flexibility and the wealth of information provided by this program have kept it in regular use by researchers around the world
  • One, two, and three-parameter logistic models
  • Samejima's model for graded responses
  • Master's partial credit model
  • Generalized partial credit model
  • Analysis of rating scale items such as open-ended essay questions
  • Analysis of multiple-choice items
  • Differential item functioning (DIF)
  • Analysis of mixtures of item types
  • Rater's-effect analysis
  • Multiple-group polytomous item response models
  • Presentation quality IRT graphics, can be imported in Word, Access, etc.
  • Detailed online HELP documentation includes syntax and examples.
TESTFACT
by R. Wood, D. Wilson, R. Gibbons, S. Schilling, E. Muraki & D. Bock
  • Marginal maximum likelihood (MML) exploratory factor analysis and classical item analysis of binary data
  • Computes tetrachoric correlations, principal factor solution, classical item descriptive statistics, fractile tables and plots
  • Handles up to 10 factors using numerical quadrature: up to 5 for non-adaptive and up to 10 for adaptive quadrature
  • Handles up to 15 factors using Monte Carlo integration techniques
  • Varimax (orthogonal) and PROMAX (oblique) rotation of factor loadings
  • Handles an important form of confirmatory factor analysis known as "bifactor" analysis: Factor pattern consists of one main factor plus group factors
  • Simulation of responses to items based on user specified parameters
  • Correction for guessing and not-reached items
  • Allows imposition of constraints on item parameter estimates
  • Handles omitted and not-presented items
  • Detailed online HELP documentation includes syntax and annotated examples.
