Out-of-sample testing is done to ensure everything is working properly, with no adjustments and with almost real-world data and samples. During the out-of-sample testing, no more modifications can be made. Trading algorithms and quantitative models are examined against both in-sample and out-...

Volvo is said to have a crash test facility where they do a number of other crash tests that aren't done by testing agencies. A reason that they scored well on the small overlap tests when they were added is that they were already doing small overlap crash tests before the IIHS started...

In sample error: training error, validation error and testing error. Out of sample error, or generalization error, is a measure of how accurately an algorithm is able to predict outcome values for previously unseen data. Because learning algorithms are evaluated on finite samples, the evaluation ...

When testing non-nested models, the asymptotic distribution theory of the ordinary like-lihood ratio statistic is not valid anymore. Several test statistics, some of them based on information criteria, have been proposed in order to test such non-nested hypotheses. Con-cerning bootstrap approaches...
(2015) introduced the so-called Fast Cross-Validation via Sequential Testing (CVST) which uses nonparametric testing together with sequential analysis in order to choose the best performing configuration on the basis of linearly increasing subsets of data. At each step, the Friedman test (1937) ...
