Hello, I run a CFA. My goodness of fit are too perfect. CFI and IFI = 1.00 and RMSEA = 0.00 What does it mean? |
|
|
How many degrees of freedom do you have? |
|
|
For a model, I have 22 degrees of freedom. When I change model adding covariances, I have 34 degrees of freedom. The "perfect goodness of fit" are the results of many CFA on the girl's sample. |

I can't really say why this occurs. If you send your input, data, output, and license number to support@statmodel.com, I will take a look at is. |

Linda - I would be very interested in hearing the reasons behind this also because I am having similar problems with a two factor CFA and dichotomous variables. |

I’m having a similar issue with perfect goodness of fit (CFI = 1, TLI = 1.002, RMSEA = 0.00) when estimating a 1-factor model for 10 dichotomous items. My sample size is small at 101. Could that be the issue? |
