Han, and Ronald K. Multiple group analysis and mixed effects designs also are available for detecting differential item functioning and modelling item and person covariates. Lertap5 the 5th version of the Laboratory of Educational Research Test Analysis Program is a comprehensive software package for classical test analysis developed for use on Windows and Macintosh computers with Microsoft Excel. This is a major Update. Graphical displays of path diagrams, factor analysis and structural equation models are created using basic graphics. Developing a common metric in item response theory.

ACER ConQuest is a computer program for fitting both unidimensional and multidimensional item response and latent regression models. It was developed by J. Lertap calculates several statistics related to decision and classification consistency, including Livingston's coefficient, the Brennan-Kane dependability index, kappa, and an estimate of p 0number of correct classifications as a proportion, derived by using the Peng-Subkoviac adaptation of Huynh's method.
S-Plus is a commercial analysis package based on the programming language S. The package includes facilities for importing and managing test data, assessing and improving the quality of data through basic test-and-item analysis, fitting an IRT model, and computing various estimates of ability.
All packages are extensively documented both for the beginner as for the professional see also the blog. Winsteps Windowsgihunopiqi.
The latest release was version 0.
Rasch Measurement Analysis Software Directory
Some of the functions are written to support a book on psychometrics as well as publications in personality research. Because of the complexity of IRT, there exist few software packages capable of calibration. This package uses item response theory methods to compute linking constants and conduct chain linking of unidimensional or multidimensional tests for multiple groups under a common item design.
Patrick Meyer at the University of Virginia. ACER ConQuest 4 also offers wider measurement and research community analysis procedures based on the most up-to-date psychometric methods of multifaceted item response models, multidimensional item response models, latent regression models and drawing plausible values.
Its output includes both spreadsheets and a detailed, narrated report document with embedded tables and figures, which can be printed and delivered to subject matter experts for item review. BMIRT is a free Java multi-purpose application program that conducts wunmira calibrations and ability estimation in a multidimensional, multi-group item response theory IRT model framework; it can fit dichotomous or polytomous models, along with mixed models.

The flexMIRT IRT software package fits a variety of unidimensional and multidimensional item response theory models also known as item factor analysis models to single-level and multilevel data in any number of groups. Confirmatory bi-factor and two-tier analyses are available for modeling item testlets.
Fit statistics are reported along with factor loadings and error variances. Various wknmira have been proposed to model this relationship, and the different calibration packages reflect this. Classical test theory is an approach to psychometric analysis that has weaker assumptions than item response theory and is more applicable to smaller sample sizes. The multidimensional methods include the least squares method and extensions of the Haebara and Stocking-Lord method using single or multiple dilation parameters for multidimensional extensions of all the unidimensional dichotomous and polytomous item response models.

The software also performs a parametric bootstrap procedure for the selection of the number of mixture components. It is only available from Assessment Systems Corporation. A number of routines for personality, psychometrics and experimental psychology. The development of WINMIRA was aimed at producing an easy to use software tool for categorical data analysis with the a variety of models including the Latent.
Examples of such software wunmira. This is a major Update.
Linking by winmra and by random equivalent-groups design are supported. Mantel-Haenszel methods are used; graphs of results are provided, including empirical DIF plots.
Polytomous mixed Rasch models. Lertap5 the 5th version of the Laboratory of Educational Research Test Analysis Program is a comprehensive software package for classical test analysis developed for use on Windows and Macintosh computers with Microsoft Excel.
The user can select from five different MCAT item selection procedures Volume, Kullback-Leibler information, Minimize the error variance of the linear combination, Minimum Angle, and Minimize the error variance of the composite score with the optimized weight.
The user specifies true examinee ability, item pools, and item selection procedures, and the program outputs selected items with item responses and ability estimates. Item responses ABCD and keys are typed or pasted into the workbook, and the output automatically populates; unlike some other programs, CITAS does not require any "running" or experience in psychometric analysis, making it accessible to school teachers and professors.
Estimation is by CML or Bayesian techniques.
