【Knowledge】What to do if the AVE is large than the shared variance

請問如果AVE大於shared variance怎麼辦呢？

Answer by Wen-Lung Shiau(蕭文龍)

有一位在英國的教授老師問了一個分析上的好問題，請問一下如果AVE大於shared variance怎麼辦呢？

Ans: A solution with simple and complex way to solve this problem.

Under a good scale validity, a simple way includes a. delete items' factor loading <0.7 b. delete large residuals C. increase sample size.

A good scale validity is the indicators of the focal construct (1) are accurate representations of the underlying construct, (2) adequately capture the multidimensional nature of the construct, (3) are diguishable from the indicors of sional nature of the construct, (3) are diguishable from the indicors,able the 5), fminal) and (4) are related to the measures of other constructs specified in the construct's nomological validity (MacKenzie et al. 2011).

A complex way is to follow the appendix A&B from MacKenzie et al. (2011) and procedures from Shiau et al.(2022).

Note 1. Please take CB-SEM (model fits) and PLS-SEM into consideration. 2 Please also take reflective and formative into a critical issues.
