Am I doing this correctly (n = length of array)? Note: The do-while loop attempts to correct for the modulo bias (see here).It adds a bit of overhead to the procedure and could be eliminated if you don't care about the low-bit bias.

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. If you have a small array with a few hundred items, you might do this. WebJan 28, 2024 · On the other hand, the Fisher’s exact test is used when the sample is small (and in this case the p p -value is exact and is not an approximation). The literature indicates that the usual rule for deciding whether the χ2 χ 2 approximation is good enough is that the Chi-square test is not appropriate when the expected values in one of the ...
