The workflow presents the research framework as a sequence of connected stages. The first stage is labelled Input Data Set. Model 1 is labelled Robust Regression Models, R R E G, with the description Provides stable parameter estimates in the presence of outliers. Model 2 is labelled Quantile-on-Quantile Regressions, Q o Q R M, with the description Identifies heterogeneous effects across different points of the outcome distribution. Model 3 is labelled Gaussian Graphical Models, G G M, with the description Map the network of conditional dependencies among selected indicators. The final stage is labelled Results and Implications, indicating the progression from data input through analytical modelling to interpretation of findings.Methodological framework
