It is an inferential statistics approach that facilitates the hypothesis testing. … WebHere, we will briefly highlight one particular assessment of model fit: the chi-square (χ 2) test. The chi-square test is unique among possible the measures of fit in SEM because it is a test of statistical significance. The chi-square value and model degrees of freedom can be used to calculate a p -value (done automatically by most SEM software).
