I have reviewed SciPy's documentation explaining their implementation formula of the Jaccard-Needham dissimilarity function https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.distance.jaccard.html#scipy.spatial.distance.jaccard. However, I cannot find anything that explains what the subscript "TF" or FT" stand for, in the formula below:

  • I believe that this function is both incorrectly documented and implemented. There is [an issue](https://github.com/scipy/scipy/issues/12174) on GitHub about this. – Ari Cooper-Davis Jul 23 '21 at 14:32

Since the documentation states this method is for Boolean arrays, T and F must stand for "true" and "false". "True" would be returned if the kth element in each string are equal, "False" otherwise.
