AMOS output always come up with different indices such has NFI, CFI, GFI, RMSEA etc. Can we say that these indices are alternatives to reliability and validity tests?
mostly, all the indices are recommended to be above .90, except the error one which is RMSEA to be less than .10 and some textbook less than .06
Regards
There are three categories fitness from Amos output:
a) Parsiminous fit: Chisquare/df
b) Absolute fit: Chisquare, RMSEA, GFI
c) Incremental fit: AGFI, CFI, TLI, NFI.
Hair et al., (1995, 2010) and Holmes smith (2006) recommend the use of at least one fitness index from each category of model fit.
