%description
A statistical hypothesis test for conditional independence. It performs
nonlinear regressions on the conditioning variable and then tests for a
vanishing covariance between the resulting residuals. It can be applied to
both univariate random variables and multivariate random vectors. Details
of the method can be found in Rajen D. Shah and Jonas Peters: The Hardness
of Conditional Independence Testing and the Generalised Covariance
Measure, Annals of Statistics 48(3), 1514--1538, 2020.
