Glance at an ackwards object

Returns a one-row data frame of top-level model metadata. For EFA and ESEM 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 (e.g., CFI and SRMR are NA for EFA; all five are NA for PCA; for ESEM, BIC is NA under estimator = "WLSMV"/"ULSMV" – these limited-information estimators have no proper log-likelihood – and populated under "ML"/"MLR"). Under a scaled-test estimator ("WLSMV"/"ULSMV"/"MLR") the CFI/TLI/RMSEA reported here are the scaled variants (see tidy.ackwards() for the rationale).
