The net promoter score (NPS) is a key indicator of customer satisfaction and loyalty. Use data on employees in the hardware product group with a college degree to develop a regression model that analyzes the effect of cognitive and noncognitive factors on NPS. Use model selection criteria to find the appropriate model for the analysis. Interpret your results with reference to well-formatted figures and tables.
