Why do some indicators (NFI, chi-square, D_g) not appear in smartpls results?
When I analyze my research data, the previous tests are all ok, only the NFI test and D_g appear as N/A, and the Chi-square appears as infinite. I suspect this is because the model is composed of second-order constructs.
I would like to know why they appear like this and how I interpret them.
If you can help me, I'd appreciate it!
Hi Vitor Trevizan
When encountering N/A or infinite values for fit measures like NFI, Chi-Square, and D_g in SmartPLS, it often relates to the complexity of your model, particularly with higher-order constructs.
My suggestions: Check for validity and reliability issues, ensuring all loadings, VIF values (ideally below 5), and discriminant validity are in order. If these are adequate, try different algorithms such as PLSc or the default PLS. For higher-order constructs, a two-stage model or simplifying your model by sequentially adding factors may help identify what's causing the issue.
