Appendix G). Initially, both CFI1 and CFI2 are equal to 1 for points on the adjustable
line. When you move the adjustable line, the fit measures in the lower left panel change
to reflect the changing position of the line.
Adjusting the Line Representing Constant C – df
EDrag the adjustable line so that CFI1 is equal to 0.950.
CFI1 is the usual CFI statistic for which the baseline model requires the observed
variables to be uncorrelated without constraining their means and variances. Points that
are below the line have CFI1 > 0.950 and those above the line have CFI1 < 0.950. That
is, the adjustable line separates the acceptable models from the unacceptable ones
according to the recommendation of Hu and Bentler (1999).
