The CFA revealed a good fit between the six observed variables and the three factors that may explain on-time performance except in the case of JFK. The use of CFA can help analysts validate constructs when theory supports a priori predictions and relationships between observed and unobserved variables.5 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
