CFA model fit

To examine the model fit we use fitmeasures() and pass a list of the names of the fit indices we would like calculated:

library(lavaan)
fitmeasures(hz.fit, c('cfi', 'rmsea', 'rmsea.ci.upper', 'bic'))
cfi          rmsea rmsea.ci.upper            bic
0.931          0.092          0.114       7595.339 

This looks OK, but the fit indices indicate the model could be improved. In particular the RMSEA figure is above 0.05. See the notes on goodness of fit statistics for more detail.
