  1. RMSEA root mean square error of approximation.
  2. These estimates are reflective of a DAG-dataset consistency evaluation, where the conditional independences illustrated above DAG were checked with the dataset. Logistic regression was implemented to calculate RMSEA. All RMSEA values were lower than 0.1 for all conditional independence statements, which lends support to the current model. Reading example (line 2): “Age is independent of SCI Severity, conditional on Etiology”.
