A −2LL bootstrapping test was also used to assess the fit of the 10-class solution; compared to a 9-class solution, the test statistic (−2LL difference = 498.29, p = 0.0000) indicates the 10-class solution provides a better fit than a solution with fewer classes.
Notes: L2 is the likelihood-ratio Chi-square statistic, which indicates the amount of the association among the variables that remains unexplained after estimating the model; the lower the value, the better the fit of the model to the data.
