the formative construct has to emit paths to (a) at least two reflective constructs

有一點需要注意: z3 E. x* Z- G C) A+ a9 r
2 \( `( K4 O% h8 |9 w L8 PAdding consequence reflective constructs (e.g., Y and Z) to the focal formative construct (e.g., X) to attain model identification makes the estimate of parameters associated with the focal construct (X) a function of the selection of the external constructs (Y and Z) (Diamantopoulos, 2006), and hence causes potential interpretational confounding (Howell et al., 2007).

以上問題在於,X's indicators與X之間關係的估計會因選擇Y and Z or 其他不同的構念而不同,但在整個nomological network來看,應該是X影響Y and Z,讓Y and Z來影響X的參數不太合理。
