RMSEA = $\sqrt{\frac{\left(X^2-\text{d}f\right)}{\text{d}f\left(N-1\right)}}$

CFI = $1-\frac{{\tau }_k}{\tau }$ dove ${\tau }_k=\max \left(X_m^2-\text{d}{f}_m,0\right)\text{e}$

${\tau }_j=\max \left(X_m^2-\text{d}{f}_m,X_b^2-\text{d}{f}_{b}0\right)$

Quindi, molto spesso: CFI = $1-\frac{\left(X_m^2-\text{d}{f}_m\right)}{{\left(X_b^2-\text{d}f\right)}_b}$

RMR = $\left[2{\displaystyle {\sum }_i{\displaystyle {\sum }_j{\left[\frac{{\left(Sij-\sigma ij\right)}^2}{k\left(k+1\right)}\right]}^{1/2}}}\right]$
