Prior Communality= Common Factor Analysis
Figure 7.3 Factor Analysis Report
The report lists the communality estimates, variance estimates, significance tests, measures of fit, rotated factor loadings, and a factor loading plot. The Rotated Factor Loadings and Factor Loading Plot suggest that Factor 1 relates to the Carbon Tetrachloride-Chloroform-Benzene-Hexane cluster of variables, and that Factor 2 relates to the Ether–1-Octanol cluster of variables. See Factor Analysis Model Fit Options for details of the information shown in the report.
