Socioeconomic status (SES) measures one’s access to social resources across various dimensions. Traditionally, studies on SES commonly use principal component analysis (PCA), a data-driven method, condense these dimensions into components, typically selecting the first represent SES. However, PCA may lack specificity for particular outcomes. Decision tree (DTA), knowledge-driven approach that identifies outcome-specific dimensions, address PCA’s weaknesses but might not comprehensively...
