CHAPTER 18CONFIDENCE INTERVALS OF MODEL RESULTSestimation, both EQTAIL and HPD confidence intervals are availablefor standardized parameter estimates.The following statement shows how to request bootstrap confidenceintervals:CINTERVAL (BOOTSTRAP);In the output, the parameters are labeled using the conventions of theMODEL command. For example, factor loadings are found in the BYstatements. Other regression coefficients are found in the ONstatements. Covariances and residual covariances are found in theWITH statements. Variances, residual variances, means, intercepts, andthresholds will be found under these headings. The scale factors used inthe estimation of models with categorical outcomes are found under theheading Scales. The CINTERVAL option is not available forTYPE=EFA.The outputs for frequentist confidence intervals and Bayesian credibilityintervals have the same format.
