0.5.4 04/19/2011

GLM pca() and plot_scores() can do cov version.

[rt.cpan.org #67557] Undo PREREQ_FATAL => 1 in Makefile.PL.

0.5.3 04/18/2011

stats_glm.t pca() test SLATEC vs. MatrixOps precision fix.

0.5.1 04/16/2011

***GLM pca() return value names updated*** to be more compatible with the literature.

GLM added plot_scores(); plot_scree() name changed to plot_screes() for consistency across plotting functions.

Updated plotting functions to default to png in Windows because GW doesn't reopen after close.

0.5.0 04/02/2011

Updated tests to use __DATA__ instead of separate test data files.

GLM added interaction_code(); bug fix for dummy_code().

GLM added ols_rptd()!

GLM added plot_residual().

GLM eval wrapped optional modules; replaced perl reverse sort with slice (-1:0).

Basic added binomial_test().

TS updated plot_season() to season_m(); deprecated a few old function names, filt_exp(), filt_ma(), and dsea().

0.4.3 04/08/2010

Distr::plot_distr() bug fix.

Kmeans::kmeans() pod update.

0.4.2 03/27/2010

rtable() added to PDL::Basic. get_data() deprecated. Preparing for transitioning to using rcols() for IO.

perldl online help support! (ie "? stdv" in perldl works)

0.4.1 02/02/2010

GLM anova anova_rptd IVNM default val matched to [].

Makefile.PL exit 0 without PDL::Lite.

TS added wmape

pod fix for CPAN

0.4.0 01/24/2010

GLM anova_rptd supports between subject factors! We are now beta!

0.3.2 01/08/2010

Kmeans kmeans CNTRD checks undef besides PDL->null. opt{V} printout update

Kmeans added which_cluster

Kmeans pca_cluster does scree plot with cutoff line

GLM logistic pod update

GLM anova anova_rptd pca plot_scree plotting options update

0.3.1 12/16/2009

Removed pms--relying on pdl-stats.sourceforge.net for web documentation instead of CPAN. Minor pod update.

GLM::ols_t removed $y->squeeze, so that edge case like ols_t on 1 obs threads properly (y[1,10]->ols_t(x[1,10]->dummy(1), {const=>0}) gives b[1,10]).

GLM::anova_rptd se fix.

GLM::anova and anova_rptd plot se fix.

PDL::Stats::TS included. ***alpha alpha*** code! Included because I'm tired of maintaining it separately from PDL::Stats.

0.3.0 12/03/2009

GLM::anova_rptd! works for purely within designs

GLM::anova bug fix--not messing up caller @ if passed @ ref in IV instead of pdl

Change prereq from PDL to PDL::Lite

Stats.pm quick-start guide update

t/stats_glm logistic test modified to use more proper numbers in x

0.2.8 11/04/2009

Fixed minor bug (mismatched nseed and self cluster pdls. oops) in switching to use cluster assignment as stop criteria. btw initial R2 now based on self instead of seeds.

0.2.7 11/04/2009

GLM::plot_scree allows directly passing NCOMP. plots cutoff line for screes if requested

kmeans stops when cluster assignment no longer changes instead of using R2CRT.

If not specified, Kmeans::pca_cluster studies scree plot to determine NCOMP

Basic::get_data STDERR message fix: data pdl o x v, NOT v x o

0.2.6 10/12/2009

anova bad value se bug fix

centroid bad value empty cluser bug fix

basic, glm, distr rid of nan and use bad value instead

0.2.5 09/17/2009

PREREQ_FATAL => 1 in Makefile.PL

added pca_cluster in Kmeans.

anova one-way bug fix.

plot_means one-way bug fix.

0.2.4 09/02/2009

added corr_table in PDL::Stats::Basic.

PDL::Stats::GLM::pca uses corr_table.

kmeans no longer quits with empty cluster. kmeans 3d threading bug fix.

use short-circuit ISBAD(a) || ISBAD(b) instead of ISGOOD(a) && ISGOOD(b) in bad value processing.

***anova interface change*** IV names now passed in \%opt instead of @ ref. I appologize for the interface change, but it matches the new method plot_means, and makes it easier to pass IVs themselves. I promise that such interface changes will be extremely rare, if at all.

anova now supports bad value in DV.

Added plot_means in PDL::Stats::GLM. anova plots highest order interaction by default.

Added plot_scree in PDL::Stats::GLM. pca does scree plot by default.

Added pca_sorti in PDL::Stats::GLM.

plot_distr in PDL::Stats::Distr accepts WIN option

Set prerequisite PDL => 2.4.4, which has bad value support by default

r2_change threads (switched to use ols_t instead of ols)

get_data which_id moved to Basic from GLM

tests grouped in PDL-Stats/t except for PDL::GSL::CDF

0.1.2 07/15/2009

Cleaned up some versioning stuff in Stats.pm

GLM::get_data TYPE default to double. MISSN handling update; set to BAD by default.

Case insensitive option passing.

0.1.1 07/14/2009

Fixed PDL::Stats::GLM::ols b_p value for b_t < 0.

0.1.0 07/13/2009

First version, released on an unsuspecting world.

PDL-Stats statistics modules in Perl Data Language
