When the results of structural equation models (SEM) are presented, they generally include one or more indices of overall model fit, the most common of which is a χ statistic. This forms the basis for other indices that are commonly reported. Although it is these other statistics that are most commonly interpreted, the degrees of freedom of the χ are essential to understanding model fit as well as the nature of the model itself.
