Other Indices of Fit - James-Mulaik-Brett Parsimonious Fit Index

This index was one of the earliest (along with the Steiger-Lind index) to compensate for model parsimony. Basically, it operates by rescaling the Bentler-Bonnet Normed fit index to compensate for model parsimony. The formula for the index is:

(128)

 = degrees of freedom for the "Null Model"

 = degrees of freedom for the k'th model

 = Bentler-Bonnet normed fit index
