Fast Kendall Tau Python. Mar 27 2018 Table 1. SciPy NumPy and Pandas correlation methods are fast comprehensive and well-documented.
These statistics are of high importance for science and technology and Python has great tools that you can use to calculate them. Do you know enough about the Kendall Rank Correlation. If the batch has a size lower than 10k values C-Cython implementation is faster than Python scipy modules 016 s and 080 s respectively.
This is a very exciting item for me to touch.
To which extent are high values on variable x are associated with either high or low values on variable y. Tau P - Q sqrt P Q T P Q U where P is the number of concordant pairs Q the number of discordant pairs T the number of ties only in x and U the number of ties only in y. Begingroup If its 312 vs 213 the number of discordant pairs here is 3 out of 3. I want to find the Kendall Tau distance between the two ie.
