Any idea how to calculate the following parameters under the Confirmatory factor analysis (CFA) (a precise method to test the unidimensionality and validity of measurements)
1. Adjusted goodness-of-fit index (AGFI)
2. Comparative fit index (CFI) and
3. Lowest root mean square residual (RMSEA).
taking into consideration the X2
thank you
Hello Abdulqadir,
A short, easy intro by David Kenny: http://davidakenny.net/cm/fit.htm
Good luck with your work.
Hello Abdulqadir,
In addition to the intro by David A. Kenny, I found the following sources useful.
Hu & Bentler, 1999
Schermelleh-Engel, Moosbrugger, & Muller, 2003
Schumacker & Lomax, 2004
The sources were cited in the attached psychometric paper in which we think we discussed EFA/CFA analysis plans and results "nicely" relative to nursing/health lit.

I used AMOS and found the below YouTube videos useful as well.

Good luck with your work!
In addition to the answers above I may add that most programs useful for CFA provide these indices as default.
