For many models 90% confidence intervals for the population RMSEA are printed. However, I cannot find an option/specification for modifying the confidence interval coverage. Is there a way to obtain a 95% and/or 99% confidence interval coverage for the RMSEA?
Actually I'm asking about having Mplus print a 95% or a 99% confidence interval (rather than a 90% confidence interval). I'm specifically talking about cases in which the theory of confidence interval construction for the RMSEA does exist and is already implemented in Mplus (just at a different level than I would prefer). Thanks.
"A confidence interval can be computed for the RMSEA. Ideally the lower value of the 90% confidence interval includes or is very near zero (or no worse than 0.05) and the upper value is not very large, i.e., less than .08. "
