CoDA Two Group Hypothesis All At Once

Performs the calculations for the three hypotheses for two diferent samples, using Compositional Data Analysis (CoDA) principles.

CoDA_2Group_All(comp1, comp2)

Arguments

comp1	A matrix of observations for composition 1. Entries must be non-zero and positive.
comp2	A matrix of observations for composition 2. Entries must be non-zero and positive.

Value

A tibble with the statistic (Q), degrees of freedom (nu), p-value, and null hypothesis (H0)
