+* New Statsample::Factor module. Include classes for extracting factors (Statsample::Factor::PCA and Statsample::Factor::PrincipalAxis) and rotate component matrix ( Statsample::Factor::Rotation subclasses). For now, only orthogonal rotations
+* New Statsample::Dataset.crosstab_with_asignation, Statsample::Dataset.one_to_many
+* New class Statsample::Permutation to produce permutations of a given array
+* New class Statsample::Histogram, with same interface as GSL one
+* New class Statsample::Test::UMannWhitney, to perform Mann-Whitney's U test. Gives z based and exact calculation of probability
+* Improved support for ReportBuilder
+* Statsample::Codification module reworked
+* Fixed bugs on Dominance Analysis classes
+* Fixed bugs on Statsample::Vector.kurtosis and Statsample::Vector.skew

* New Distribution module, based on statistics2.rb by Shin-ichiro HARA. Replaces all instances of GSL distributions pdf and cdf calculations for native calculation.
* New Maximum Likehood Estimation for Logit, Probit and Normal Distribution using Von Tessin(2005) algorithm. See MLE class and subclasses for more information.
* New Binomial regression subclasses (Logit and Probit), usign MLE class
* Added tests for gsl, Distribution, MLE and Logit
