Returns a one-row data frame of top-level model metadata. For EFA
(exploratory factor analysis) and ESEM (exploratory structural equation
modeling) objects, fit indices at the deepest converged level are included.
The same five columns (CFI, TLI, RMSEA, SRMR, BIC) are present
across all engines. Columns unavailable for a given engine or estimator are
NA. For example, CFI and SRMR are NA for EFA, and all five are NA
for PCA (principal component analysis). For ESEM, BIC is NA under
estimator = "WLSMV" or "ULSMV", because these limited-information
estimators have no proper log-likelihood, and it is populated under "ML"
or "MLR". Under a scaled-test estimator
("WLSMV", "ULSMV", or "MLR") the CFI, TLI, and RMSEA reported
here are the scaled variants (see tidy.ackwards() for the rationale).
