摘要：The aim of this work is to understand the relationship between the overall job satisfaction and the facet job satisfaction, using a comprehensive Italian social cooperatives workers dataset. On this issue, recent works have explored how ensemble learning like Random Forest and TreeBoost can be used to assess the importance of potential predictors in the job satisfaction. Taking a similar way, in this study we use a tailored data mining approach for hierarchical data, namely a new algorithm called CRAGGING, shedding some light about the drivers of Job Satisfaction. To do this we use the variable importance measure designed for the CRAGGING and then we grow a synthetic model to relate the overall job satisfaction with corresponding facets, providing sufficient evidence about good accuracy and less complexity of the model leading to simple and direct interpretation.
