The structural model diagram features several labeled components: GPI, PP, GU, PW, and PE. Each component is connected to specific labeled items: GPI is connected to GPI1, GPI4, GPI3, GPI6, GPI5, and GPI2; PP is connected to PP7, PP6, PP5, PP4, PP3, PP2, and PP1; GU is connected to GU1, GU6, GU7, GU8, and GU9; PW is connected to PW2, PW3, PW5, PW6, PW8, and PW9; PE is connected to PE2, PE4, PE5, PE6, PE7, PE8, PE9, and PE10. Arrows indicate the direction of influence or relationship between these components, with numerical values representing the strength of these connections.
