check_Xvar

Users should always specify Xvar as "NAME_SIMPLEX",
which means before log-ratio transformations.

internal

Provides methods for interpreting CoDa (Compositional Data) regression models along the lines of "Pairwise share ratio interpretations of compositional regression models" (Dargel and Thomas-Agnan 2024) <doi:10.1016/j.csda.2024.107945>.
The new methods include variation scenarios, elasticities, elasticity differences and share ratio elasticities.
These tools are independent of log-ratio transformations and allow an interpretation in the original space of shares.
'CoDaImpact' is designed to be used with the 'compositions' package and its ecosystem.
