Export node information from abnFit objects fitted with MLE (mixed effects)
export_abnFit_mle_grouped_nodes(object, ...)A named list with two components: variables and parameters. Variables is an array where each element represents a variable with its metadata. Parameters is an array where each element represents a parameter, including both fixed-effect coefficients and random-effect variance components.
An object of class abnFit fitted with method = "mle" and group.var specified.
Additional arguments (currently unused)
This function extracts node parameterisation information from abnFit objects that were fitted using the Maximum Likelihood Estimation (MLE) approach WITH mixed-effects (i.e., group.var was specified).
For mixed-effects models, the structure includes:
Fixed effects: Population-level intercepts and coefficients
Random effects: Group-level variance components (sigma, sigma_alpha)
The export format follows the same variables/parameters structure, but parameters will include both fixed-effect coefficients and random-effect variance components.
