Correspondence between relative parameters estimated using gLV and cLV on three datasets.

Each box plot displays the distribution of observed community size (i.e. N(t)) across all samples, rescaled such that . Scatter plots display the relative parameters estimated by cLV (y-axis), and the corresponding difference in parameters of gLV (x-axis). cLV better approximates interactions inferred using gLV when the variability in concentrations is low, matching theoretical expectations. A strong correspondence is observed between external perturbations across all datasets.
