 homals-0.9-0-on-cran This package implements the methods discussed in Gifi, Nonlinear Multivariate Analysis, Wiley, 1990. In the Gifi terminology it covers homals, princals, canals, morals, criminals, and overals. The R implementation fills several gaps in Gifi, adding multiple ordinal, numerical, and polynomial data transformations. Differences with previous CRAN version: a. More R-like with S3 classes, namespace, print, plot, plot3d, summary, predict methods b. (Much) better documented functions and data sets c. Dynamic three-d plot using rgl d. Static three-d plot using scatterplot3d e. Predict method that counts "correct" classifications f. Many bugs fixed A paper describing the technique and implementation, with many examples, is almost ready. There is a preprint at http://gifi.stat.ucla.edu/homalsR.pdf 0 0 1970-01-01 00:00 No Moderation
 homals-0.9-3-available Homals 0.9-3 is on R-forge and soon on CRAN: - bugs for data with missing values and various active/sets combintations fixed - checks for active/sets arguments added - loadings plot added (2D and 3D) - verbose argument added for printing out iteration results 0 0 1970-01-01 00:00 No Moderation
 psychor-multiple-package PsychoR is now provided as a multiple package project. So far it includes homals for Gifi-models and anacor for correspondence analysis. Both are already available on CRAN. In addition, a first beta version of smacof is checked in which will be completed soon. 0 0 1970-01-01 00:00 No Moderation
 homals--anacor--smacof New versions of homals and anacor are available on CRAN. Vignettes are included. A first smacof beta version for multidimensional scaling (MDS) is available on R-forge. 1 4 2014-09-07 16:57 No Moderation
 smacof-0.9-0-submitted-to-cran smacof provides the following approaches of multidimensional scaling (MDS) based on stress minimization by means of majorization: Simple smacof on symmetric dissimilarity matrices, smacof for rectangular matrices (unfolding models), smacof with constraints on the configuration, three-way smacof for individual differences (including constraints for idioscal, indscal, and identity), and spherical smacof (primal and dual algorithm). Each of these approaches is implemented in a metric and nonmetric manner including primary, secondary, and tertiary approaches for tie handling. Package vignette is included. 0 0 1970-01-01 00:00 No Moderation
 smacof-1.2-0 A smacof update is available on R-forge. It includes jackknife and permutation tests for MDS. 0 0 1970-01-01 00:00 No Moderation
