toulouse_retail

This data set provides an example for the use of CoDa models in geomarketing applications.
The data is simulated, but realistic in the sense that the parameters used for the simulation
were estimated on a real, but confidential data set (Dargel and Thomas-Agnan 2024).

data

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.
