Methodlogy behind the tests

Postby ptang456 » Mon Aug 04, 2014 14:58

Hello, I'm trying to find on the website the methodology behind how Orange does all the tests i.e. Cross Validation, Random, Leave One Out etc, and how what algorythm the Regression Tree is based on (I understand there are different methodologies).
Can someone point me in the right direction on the website?
Thanks

The testing methods ate documented here, although it only documents the API and does not discus the details of the algorithms. They are standard implementations so refer to wikipedia.

The regression tree's documentation might similarly be unintelligible, but the default behavior is that of a recursive partitioning algorithm with MSE as a split score.
