SOFTWARE COMPONENTS and APPLICATIONS
LCA / OLCA / Latent Multidimensional Structure
CONCOV
/ Nonparametrically estimates the conditional covariance curve for each item pair as a function of the underlying composite latent ability best measured by the total test score. [ / US$ 100,00DETECT
/ Nonparametrically provides a detailed dimensional description of a test in which the items are grouped around several underlying psychological or cognitive constructs. [ / US$ 150,00DIMTEST / Poly-DIMTEST
/ Implements a hypothesis testing procedure that assesses lack of latent unidimensionality for dichotomously scored educational or psychological test. [ / US$ 200,00HCA/CCPROX
/ Performs a latent nonparametric multidimensionality-sensititve hierarchical cluster analysis on either dichotomously or polytomously scored items. [ / US$ 125,00Suddan
/ Analyze complex data sets [ / US$ 160,00LatentGold
/ Includes new, state-of-the-art technical features like Bayes constants to help avoid boundary solutions, bivariate residuals to diagnose local dependence, and automatic generation of multiple start values. Parameter estimate standard errors are supplied. [ / US$ 695,00LLCA
/ LLCA, for Located Latent Class Analysis, estimates probit unidimensional latent class models, as described in Uebersax (1993). This is a discrete latent trait model, similar to the logistic unidimensional latent class (e.g., Lindsay, Clogg, and Grego, 1991), but based on a probit, rather than logistic assumptions. [ / AvailableMLLSA
/ MLLSA (Maximum Likelihood Latent Structure Analysis), written by the late Clifford Clogg, is a bit old but still a good way to learn LCA. / AvailableIRT / Rasch
BILOG
/ Estimates IRT Parameters for the 1-, 2-, or 3-parameter logistic model using marginal maximum-likelihood. [ / US$ 250,00LOGIMA
/ Estimates parameters of loglinear IRT models including partial credit models, multidimensional partial credit models, and multidimensional polytomous models. / US$ 280,00ParScale
/ Performs IRT scaling, item analysis, and scoring of rating scale data. [ / US$ 250,00XCALIBRE
/ Marginal maximum-likelihood IRT parameter estimation with small numbers of examinees or short tests, for the 2- and 3-parameter IRT model. [ / US$ 399,00Demo
LPCM
/ Applies linear partial-credit models to estimate various Rasch models, including the linear logistic test model and multidimensional models. [ / US$ 380,00Demo
RASCAL
/ Estimates Rasch parameters for dichotomous data with linear re-scaling of parameter, "fixing" selected item parameters, and centering on item or person parameters. [ / US$ 299,00Demo
WinMira
/ Offers latent class analysis and estimation of numerous Rasch models based on dichotomous data. [ / US$ 200,00Demo
WinSteps
/ RASCH Analysis [ / US$ 195,00Demo
GGUM2004
/ IRT; Generalized Graded Unfolding Model / AvailableETIRM
/ Performs estimation three parameter IRT models and one and two parameter logistic models. [ / AvailableTestgraf
/ TestGraf98 is designed to aid the development, evaluation, and use of multiple choice examinations, psychological scales, questionnaires, and other types of data [ / AvailableISOP

/ [ / EUR 220,00Demo
MSP
/ Analyzes dichotomous and polytomous items using nonparametric cumulative item response theory. [ / US$ 480,00Demo
