Functions for testing if the covariance structure of 2dimensional data (e.g. samples of surfaces X_i = X_i(s,t)) is separable, i.e. if covariance(X) = C_1 x C_2. A complete descriptions of the implemented tests can be found in the paper Aston, John A. D.; Pigoli, Davide; Tavakoli, Shahin. Tests for separability in nonparametric covariance operators of random surfaces. Ann. Statist. 45 (2017), no. 4, 14311461. <doi:10.1214/16AOS1495> <https://projecteuclid.org/euclid.aos/1498636862> <arXiv:1505.02023>.
