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$ 100,00

DETECT

/ Nonparametrically provides a detailed dimensional description of a test in which the items are grouped around several underlying psychological or cognitive constructs. [ / US$ 150,00

DIMTEST / Poly-DIMTEST

/ Implements a hypothesis testing procedure that assesses lack of latent unidimensionality for dichotomously scored educational or psychological test. [ / US$ 200,00

HCA/CCPROX

/ Performs a latent nonparametric multidimensionality-sensititve hierarchical cluster analysis on either dichotomously or polytomously scored items. [ / US$ 125,00

Suddan

/ Analyze complex data sets [ / US$ 160,00

LatentGold

/ 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$ 695,00

LLCA

/ 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.

BILOG

/ Estimates IRT Parameters for the 1-, 2-, or 3-parameter logistic model using marginal maximum-likelihood. [ / US$ 250,00

LOGIMA

/ Estimates parameters of loglinear IRT models including partial credit models, multidimensional partial credit models, and multidimensional polytomous models. / US$ 280,00

ParScale

/ Performs IRT scaling, item analysis, and scoring of rating scale data. [ / US$ 250,00
