public class PairedCorrectedTTester
Behaves the same as PairedTTester, only it uses the corrected resampled t-test statistic.
For more information see: Claude Nadeau, Yoshua Bengio (2001). Inference for the Generalization Error. Machine Learning.. BibTeX:@article{Nadeau2001, author = {Claude Nadeau and Yoshua Bengio}, journal = {Machine Learning}, title = {Inference for the Generalization Error}, year = {2001}, PDF = {http://www.iro.umontreal.ca/\~lisa/bib/pub_subject/comparative/pointeurs/nadeau_MLJ1597.pdf} }Valid options are:
-D <index,index2-index4,...> Specify list of columns that specify a unique dataset. First and last are valid indexes. (default none)
-R <index> Set the index of the column containing the run number
-F <index> Set the index of the column containing the fold number
-G <index1,index2-index4,...> Specify list of columns that specify a unique 'result generator' (eg: classifier name and options). First and last are valid indexes. (default none)
-S <significance level> Set the significance level for comparisons (default 0.05)
-V Show standard deviations
-L Produce table comparisons in Latex table format
-csv Produce table comparisons in CSV table format
-html Produce table comparisons in HTML table format
-significance Produce table comparisons with only the significance values
-gnuplot Produce table comparisons output suitable for GNUPlot
