These are discussed below: Chisq: The model Chi-squared assesses overall fit and the discrepancy between the sample and fitted covariance matrices. Its p-value should be > .05 (i.e., the hypothesis of a perfect fit cannot be rejected). WebThe chi-square goodness of fit test assesses the differences between the observed and expected proportions. Because the p-value is less than the significance level, we reject the null hypothesis and conclude that these differences are statistically significant. eagles player barnett
