Fast estimation of Kendall's Tau and conditional Kendall's Tau matrices under structural assumptions
Kendall’s tau and conditional Kendall’s tau matrices are multivariate (conditional) dependence measures between the components of a random vector. For large dimensions, available estimators are computationally expensive and can be improved by averaging ...

On kernel-based estimation of conditional Kendall’s tau: finite-distance bounds and asymptotic behavior [PDF]
We study nonparametric estimators of conditional Kendall’s tau, a measure of concordance between two random variables given some covariates. We prove non-asymptotic pointwise and uniform bounds, that hold with high probabilities.

Testing for Changes in Kendall's Tau [PDF]
For a bivariate time series $((X_i,Y_i))_{i=1,...,n}$ we want to detect whether the correlation between $X_i$ and $Y_i$ stays constant for all $i = 1,...,n$.

Study of partial and average conditional Kendall’s tau [PDF]
When the interest is in studying conditional dependencies, and more precisely the strength of conditional dependencies, some kind of averaging over the conditioning random vector may be needed.

An LSH Index for Computing Kendall's Tau over Top-k Lists [PDF]
We consider the problem of similarity search within a set of top-k lists under the Kendall's Tau distance function. This distance describes how related two rankings are in terms of concordantly and discordantly ordered items.

Can point-of-care ultrasound predict the difficulty in intubation? – A prospective observational study [PDF]
Background and Aims: Airway ultrasonography (USG) parameters have been used to predict difficult tracheal intubation. However, the available literature on this topic is still controversial.

Kendall's tau for autocorrelation
The authors show how Kendall's tau can be adapted to test against serial dependence in a univariate time series context. They provide formulas for the mean and variance of circular and non-circular versions of this statistic, and they prove its asymptotic normality.
