Fisher-yates test
Web3 Development of Fisher’s exact test As Yates points out in his first paragraph, the χ2 test was famously in-troduced by Pearson (1900), with Fisher (1922) modifying the degrees … WebMar 6, 2011 · This function is equivalent to X(RANDPERM(LENGTH(X)), but 50% to 85% faster. It uses D.E. Knuth's shuffle algorithm (also called Fisher-Yates) and the cute KISS random number generator (G. Marsaglia). While RANDPERM needs 2*LENGTH(X)*8 bytes as temporary memory, SHUFFLE needs just a fixed small number of bytes. 1.

WebTime complexity is O(N log N), same as quick sort. Space complexity is O(N). This is not as efficient as a Fischer Yates shuffle but, in my opinion, the code is significantly shorter and more functional. If you have a large array you should certainly use Fischer Yates.

The algorithm effectively puts all the elements into a hat; it continually determines the next element by randomly drawing an element from the hat until no elements … See more The Fisher–Yates shuffle, in its original form, was described in 1938 by Ronald Fisher and Frank Yates in their book Statistical tables for biological, agricultural and medical research. Their description of the algorithm used … See more The "inside-out" algorithm The Fisher–Yates shuffle, as implemented by Durstenfeld, is an in-place shuffle. That is, given a preinitialized array, it shuffles the elements of the array in place, rather than producing a shuffled copy of the array.
