Package Bchron updated to version 3.1 with previous version 3.0 dated 2009-12-09

Title: Bayesian chronologies via compound Poisson-Gamma processes.
Description: This package takes dating information to produce joint chronological reconstructions for age-depth data. The package allows for: radiocarbon and non-radiocarbon depths, thickness errors, outlying dates, multiple calibration curves, and event prediction. It also produces some pretty pictures, and writes all output to files to allow for further analysis (eg palaeoclimate reconstruction). There is a menu system for users, as well as a command line interface for advanced and/or batch processing. Latest version contains IntCal09 data.

Package monomvn updated to version 1.8 with previous version 1.7-4 dated 2009-11-17

Title: Estimation for multivariate normal and Student-t data with monotone missingness
Description: Estimation of multivariate normal and student-t data of arbitrary dimension where the pattern of missing data is monotone. Through the use of parsimonious/shrinkage regressions (plsr, pcr, lasso, ridge, etc.), where standard regressions fail, the package can handle a nearly arbitrary amount of missing data. The current version supports maximum likelihood inference and a full Bayesian approach employing scale-mixtures for the lasso (double-exponential) and Normal-Gamma priors, and Student-t errors. Monotone data augmentation extends this Bayesian approach to arbitrary missingness patterns. A fully functional standalone interface to the Bayesian lasso (from Park & Casella), Normal-Gamma (from Griffin & Brown), and ridge regression with model selection via Reversible Jump, and student-t errors (from Geweke) is also provided

Package corpcor updated to version 1.5.5 with previous version 1.5.4 dated 2009-12-16

Title: Efficient Estimation of Covariance and (Partial) Correlation
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, partial variances, and regression coefficients. The inverse of the covariance and correlation matrix can be efficiently computed, and 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: SAGA Geoprocessing and Terrain Analysis in R
Description: RSAGA provides access to geocomputing and terrain analysis functions of SAGA from within R by running the command line version of SAGA. In addition, several R functions for handling and manipulating ASCII grids are provided, including a flexible framework for applying local functions (including predict methods of fitted models) or focal functions to multiple grids. SAGA is available under GPL via http://sourceforge.net/projects/saga-gis/.

Package bclust updated to version 1.1 with previous version 1.0 dated 2009-08-04

Title: Bayesian clustering using spike-and-slab hierarchical model, suitable for clustering high-dimensional data.
Description: The package builds a dendrogram with log posterior as a natural distance defined by the model. It is also capable to computing Bayesian discrimination probabilities equivalent to the implemented Bayesian clustering. Spike-and-Slab models are adopted in a way to be able to produce an importance measure for clustering and discriminant variables. The method works properly for data with small sample size and high dimensions. The model parameter estimation maybe difficult, depending on data structure and the chosen distribution family.
