df of the test. As expected, the distribution of the test-statistic conformed to a χ2 distribution with an average approaching the df (Supplementary Figure 32). Calculated CFI values were also highly consistent with those observed using the CFI statistic provided by lavaan when using raw data (Supplementary Figure 33, Supplementary Table 20). Calculated AIC values were not contrasted with those obtained using the lavaan package in R in the simulations below as the software uses a formula that includes a log-likelihood estimate contingent on the provided sample size.
