Package plink updated to version 1.2-5 with previous version 1.2-4 dated 2010-07-26

Title: IRT Separate Calibration Linking Methods
Description: 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. The unidimensional methods include the Mean/Mean, Mean/Sigma, Haebara, and Stocking-Lord methods for dichotomous (1PL, 2PL and 3PL) and/or polytomous (graded response, partial credit/generalized partial credit, nominal, and multiple-choice model) items. The multidimensional methods include the Reckase-Martineau method and extensions of the Haebara and Stocking-Lord method using a single dilation parameter, multiple dilation parameters, or the Oshima, Davey, & Lee approach for multidimensional extensions of all the unidimensional dichotomous and polytomous item response models. The package also includes functions for importing item and/or ability parameters from common IRT software, conducting IRT true score and observed score equating, and plotting item response curves/surfaces, vector plots, and comparison plots for examining parameter drift.

Package VecStatGraphs3D updated to version 1.1 with previous version 1.0 dated 2010-07-30

Title: Vector analysis using graphical and analytical methods in 3D.
Description: This package performs a 3D statistical analysis, both numerical and graphic, of a set of vectors. Since a vector has three components (a module and two angles) vector analysis is performed in two stages: modules are analyzed by means of linear statistics and orientations are analyzed by spherical statistics. Tests and spherical statistic parameters have associated a full range of graphing: vector maps, density maps, distribution modules and angles. The tests, spherical statistic parameters and graphs allow us detecting another distribution properties (I.e. anisotropy) and outliers.

Since a vector has two components (module and azimuth) vector analysis is performed in three stages: modules are analyzed by means of linear statistics, azimuths are analyzed by circular statistics, and the joint analysis of modules and azimuths is done using density maps that allow detecting another distribution properties (I.e. anisotropy) and outliers. Tests and circular statistic parameters have associated a full range of graphing: histograms, maps of distributions, point maps, vector maps, density maps, distribution modules and azimuths.

Package TripleR updated to version 0.4.3 with previous version 0.4 dated 2010-07-24

Title: Social Relation Model (SRM) analyses for single or multiple round-robin groups
Description: Social Relation Model (SRM) analyses for single or multiple round-robin groups are performed. These analyses are either based on one manifest variable, one latent construct measured by two manifest variables, two manifest variables and their bivariate relations, or two latent constructs each measured by two manifest variables. Within-group t-tests for variance components and covariances are provided for single groups, between-groups t-tests for multiple groups. Preliminary handling for missing values is provided.

Package Deducer updated to version 0.4-0 with previous version 0.3-3 dated 2010-06-21

Title: Deducer
Description: An intuitive, cross-platform graphical data analysis system. It uses menus and dialogs to guide the user efficiently through the data manipulation and analysis process, and has an excel like spreadsheet for easy data frame visualization and editing. Deducer works best when used with the Java based R GUI JGR, but the dialogs can be called from the command line. Dialogs have also been integrated into the Windows Rgui.
