In compositional data analysis as studied by John Aitchison, the analogue of simple linear regression is $$Y_i = \alpha\oplus\beta\odot X_i \oplus \epsilon_i$$ Here, $Y_i = [y_1,...,y_n]$ is the response, $X_i \in \mathbb{R}$ is a covariate, $\alpha, \beta = [\alpha_1,...,\alpha_n], [\beta_1,...,\beta_n]$ are the parameters, and $\epsilon = [\epsilon_1,...,\epsilon_n]$ is a random component.
Here, $\oplus$ and $\odot$ mean pertubation and powering.
Question: What is the interpretation of the parameters in this model? If I estimate $\alpha$ and $\beta$ using log-ratio analysis, how do I interpret their meaning and communicate that to laymen?
