Compositional Data Two-Sample Test of Equal Distributions

Two-sample tests of equal distributions for compositional data, with zero values present. The p-value is computed via permutations. The relevant papers are Stewart C., Iverson S. and Field C. (2014). "Testing for a diet change using fatty acid signatures". Environmental and Ecological Statistics, and Sevinc V. and Tsagris. M. (2026).
