statistics-1.8.4

Summary of important user-visible changes for statistics 1.8.4:

Important Notice:

1. Minimum datatypes package version required is now 1.2.6
2. Incompatibility with the nan and tablicious packages

There are 2 new classdefs introduced in this release:

• LinearModel: object-oriented linear regression model class, returned by fitlm (#444)
• anova — object-oriented interface for analysis of variance, built on anova1, anova2, and anovan with a MATLAB-compatible object API (#450)

Other improvements:

• parseWilkinsonFormula: fix power-term resolution from a base table column (#445)
• anova1 add support for categorical arrays as grouping variables

Backward compatibility notice!
fitlm now returns a LinearModel object; the previous [TAB, STATS] = fitlm (...) output form is no longer supported (#443, #446)

2. Additional dependency to the datatypes package
3. Incompatibility with the nan and tablicious packages

News:

• New makima function
• Updated libsvm library to version 3.36
• Updated documentation and many new demos, especially for class methods and properties

statistics-1.7.7

Summary of important user-visible changes for statistics 1.7.7

Important Notice:
mean, median, std, var, and mad shadow core Octave's functions before Octave 9.1
incompatibility with the nan package

News:

• Updated documentation #263, #285
• Minor fixes in cvpartition and pca #268, #269, #279

statistics-1.7.6

Summary of important user-visible changes for statistics 1.7.6

Important Notice:
mean, median, std, var, and mad shadow core Octave's functions before Octave 9.1
incompatibility with the nan package

News:

• There are 2 new functions (factoran and multiway) introduced in this release.
• Updated documentation and demos for distribution objects.
• cvpartition and crossval are now fully MATLAB compatible.
• Several bug fixes related to various issues #232, #226
• ClassificationKNN can use either 'exhaustive' or 'kdtree' search methods for prediction.

statistics-1.7.5

Summary of important user-visible changes for statistics 1.7.5

Important Notice:
mean, median, std, var, and mad shadow core Octave's functions before Octave 9.1
incompatibility with the nan package

News:

• There are 2 new functions and 4 new classdefs introduced in this release.
• Several bug fixes related to various issues #183, #199, #200, #203, #204, #212, #215
• Fixed the slow kd-tree implementation in knnsearch and rangesearch functions.

Note!

1. The old style cvpartition class has been deprecated in favor of the newly introduced classdef implementation. There is a limited brake in backwards compatibility, so old code might need some tweaking before working again. The new cvpartition has many new features and is mostly MATLAB compatible.
2. crossval needs attention, see issue #217.
