Comparison of true (supplied) and recovered marginal distributions for each of the three dependent (top) and independent (bottom) variables, along with the centers of the Gaussian kernels, which were computed using the LASSO method detailed in section “Gathering Model Inputs: Marginal Distributions”. Note, the marginals for the dependent variables were generated after separate runs of the fitting algorithm using all three independent variables. The marginal distributions shown for the independent variables were obtained from the fit using reaction time (the marginal fits of the independent variables using the other two dependent variables displayed an equal level of accuracy). In addition to the fidelity between the LASSO model (recovered) and data-generated (supplied) marginals, we also observe that the KDE and ML methods for recovering marginals were able to resolve a variety of detail and non-Gaussian structure within the distributions.
