A permutation test (also called re-randomization test) is an exact statistical hypothesis test making use of the proof by contradiction. A permutation test involves two or more samples. The null hypothesis is that all samples come from the same distribution . Under the null hypothesis, the distribution of the test statistic is obtained by calculating all possible values of the test statistic under possible rearrangements of the observed data. Permutation tests are, therefore, a form of WebbProbability with permutations and combinations Get 3 of 4 questions to level up!

WebbProbability is the foundation and language needed for most statistics. Probability deals with uncertainty in the real world. In Machine Learning and Data Science whatever the result we conclude is also uncertain in nature and the best way to interpret those results is to apply knowledge of probability.

Permutations take into consideration the order of the subset whereas combinations do not. Combinations and permutations are extremely important if you’re working on network security, pattern analysis, operations research, and more.

WebbPermutation-based probabilities are calculated as the proportion of permutations in which the computed value of the test statistic is equal to or more extreme than the actual value. This calculation is easier to do mentally if the denominator is a multiple of ten, such as 1,000, though computationally there is no requirement to do this.
