Title: Multidimensional Item Response Theory
Diff between mirt versions 0.2.3 dated 2012-05-02 and 0.2.4 dated 2012-05-09
Description: Analysis of dichotomous and polychotomous response data
using latent trait models under the Item Response Theory
paradigm. Includes the multivariate two- and three-parameter
logistic models, confirmatory bifactor analysis, polytomous
exploratory and confirmatory item response models which may
include polynomial or product constructed factors, and
partially-compensatory item response modeling in conjunction
with other IRT models.

Description: FlexMix implements a general framework for finite mixtures
of regression models using the EM algorithm. FlexMix provides
the E-step and all data handling, while the M-step can be
supplied by the user to easily define new models. Existing
drivers implement mixtures of standard linear models,
generalized linear models and model-based clustering.

Title: Efficient Estimation of Covariance and (Partial) Correlation
Diff between corpcor versions 1.6.2 dated 2012-01-22 and 1.6.3 dated 2012-05-09
Description: This package implements a James-Stein-type shrinkage
estimator for the covariance matrix, with separate shrinkage
for variances and correlations. The details of the method are
explained in Sch\"afer and Strimmer (2005) and Opgen-Rhein and
Strimmer (2007). The approach is both computationally as well
as statistically very efficient, it is applicable to "small n,
large p" data, and always returns a positive definite and
well-conditioned covariance matrix. In addition to inferring
the covariance matrix the package also provides shrinkage
estimators for partial correlations and partial variances. The
inverse of the covariance and correlation matrix can be
efficiently computed, as well as any arbitrary power of the
shrinkage correlation matrix. Furthermore, functions are
available for fast singular value decomposition, for computing
the pseudoinverse, and for checking the rank and positive
definiteness of a matrix.

Title: Choice Modeling in R
Diff between ChoiceModelR versions 1.0 dated 2012-01-04 and 1.1 dated 2012-05-09
Description: Implements an MCMC algorithm to estimate a hierarchical
multinomial logit model with a normal heterogeneity
distribution. The algorithm uses a hybrid Gibbs Sampler with a
random walk metropolis step for the MNL coefficients for each
unit. Dependent variable may be discrete or continuous.
Independent variables may be discrete or continuous with
optional order constraints. Means of the distribution of
heterogeneity can optionally be modeled as a linear function of
unit characteristics variables.

Title: A Collection of Database, Data Structure, Visualization, and
Utility Functions for R
Diff between caroline versions 0.6.9 dated 2012-02-09 and 0.7.2 dated 2012-05-09
Description: The caroline R library contains dozens of functions useful
for: database migration (dbWriteTable2), database style joins &
aggregation (nerge, groupBy & bestBy), data structure
conversion (nv, tab2df), legend table making (sstable &
leghead), plot annotation (labsegs & mvlabs), data
visualization (violins, pies & raPlot), character string
manipulation (m & pad), file I/O (write.delim), batch scripting
(cmdArgsToVariables) and many more. The package's greatest
contributions lie in the database style merge, aggregation and
interface functions as well as in it's extensive use and
propagation of row, column and vector names in most functions.
