1.2.2: ------------------------------------------------------------------- ** Fixed documentation of dendogram and hist3 to work with TexInfo 5. Summary of important user-visible changes for statistics 1.2.1: ------------------------------------------------------------------- ** The following functions are new: pcares pcacov runstest stepwisefit hist3 ** dendogram now returns the leaf node numbers and order that the nodes were displayed in. ** New faster implementation of princomp. Summary of important user-visible changes for statistics 1.2.0: ------------------------------------------------------------------- ** The following functions are new: regress_gp dendogram plsregress ** New functions for the generalized extreme value (GEV) distribution: gevcdf gevfit gevfit_lmom gevinv gevlike gevpdf gevrnd gevstat ** The interface of the following functions has been modified: mvnrnd ** `kmeans' has been fixed to deal with clusters that contain only one element. ** `normplot' has been fixed to avoid use of functions that have been removed from Octave core. Also, the plot produced should now display some aesthetic elements and appropriate legends. ** The help text of `mvtrnd' has been improved. ** Package is no longer autoloaded. Summary of important user-visible changes for statistics 1.1.3: ------------------------------------------------------------------- ** The following functions are new in 1.1.3: copularnd mvtrnd ** The functions mnpdf and mnrnd are now also usable for greater numbers of categories for which the rows do not exactly sum to 1. Summary of important user-visible changes for statistics 1.1.2: ------------------------------------------------------------------- ** The following functions are new in 1.1.2: mnpdf mnrnd ** The package is now dependent on the io package (version 1.0.18 or later) since the functions that it depended of from miscellaneous package have been moved to io. ** The function `kmeans' now accepts the 'emptyaction' property with the 'singleton' value. This allows for the kmeans algorithm to handle empty cluster better. It also throws an error if the user does not request an empty cluster handling, and there is an empty cluster. Plus, the returned items are now a closer match to Matlab. Summary of important user-visible changes for statistics 1.1.1: ------------------------------------------------------------------- ** The following functions are new in 1.1.1: monotone_smooth kmeans jackknife ** Bug fixes on the functions: normalise_distribution combnk repanova ** The following functions were removed since equivalents are now part of GNU octave core: zscore ** boxplot.m now returns a structure with handles to the plot elemenets. Summary of important user-visible changes for statistics 1.1.0: ------------------------------------------------------------------- ** IMPORTANT note about `fstat' shadowing core library function: GNU octave's 3.2 release added a new function `fstat' to return information of a file. Statistics' `fstat' computes F mean and variance. Since MatLab's `fstat' is the equivalent to statistics' `fstat' (not to core's `fstat'), and to avoid problems with the statistics package, `fstat' has been deprecated in octave 3.4 and will be removed in Octave 3.8. In the mean time, please ignore this warning when installing the package. ** The following functions are new in 1.1.0: normalise_distribution repanova combnk ** The following functions were removed since equivalents are now part of GNU octave core: prctile ** The __tbl_delim__ function is now private. ** The function `boxplot' now accepts named arguments. ** Bug fixes on the functions: harmmean nanmax nanmin regress ** Small improvements on help text.
