WebBesides the intensity of the shifts in the relative abundance of the soil microbiome provided by the GJAM regression coefficients, the relevance of the different microbes for the soil community was evaluated in terms of the centered log-ratio (CLR) transformed abundance (Leite and Kuramae, 2024). CLR transformation informs the relevance of the ... WebOct 11, 2024 · The basic concept and data transformation in compositional data analysis is thus the logratio, the logarithm of pairwise ratios, with the log-transformation serving several purposes: 1. Taking the data into real space, 2. Turning interval differences on the log-scale into percentage differences when back-transformed to the original ratio scale, 3.
