Does AMOS report RMSEA, CFI, NNFI, and chi-square? I think most academic papers report these indices rather than AVE. I use these indices to judge discriminant validy by comparing one-factor and two factor models. AVE?! I am afraid that I could not help.
yes, RMSEA,CFI,GFI,CHIsquare are all reflected. But I use them to show the model fit. The way you mentioned in judging discriminant validity was new to me. Thank you anyway, I will ask professor tomorrow and give his reply later.
据我所知,无论是基于maximum likelihood estimation的需要编程的lisrel,还是直接图示化的amos,或是基于Partial least square的PLS软件都不能直接在程序中通过语句和命令来计算AVE值。AVE值需要依据计算公式利用其他数据,手动进行计算。
具体的计算公式可见:
