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.

- 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.

0.2.3 08/24/2009
- ***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.
