Hi, Bengt/Linda.
Can you please explain to me the difference between RMSEA and RMSR? My understanding is that Mplus reports RMSR in EFA models. I don't know how it differs from RMSEA, however.
Best,
Ethan |

| You can find the formulas for all fit statistics in Mplus in Techncal Appendix 5 which is on the website. |

| Hi. I'm running a very large simulation study with Mplus and wanted to know if there was anyway that I could call the Mplus program from within another program or from a DOS .BAT file so that I could automate the process and avoid having to submit each of my set of simulation commands individually. Thank-you. |

You can run Mplus from a DOS .BAT file, for example, the .BAT file would contain the following commands:
call Mplus file1.inp
call Mplus file2.inp
where file1.inp and file2.inp are input files. |

| I suspected as much. Thank-you very much for the speedy response!!!!! One further question: from which directory should I run the mplus directory itself? |
|
|
|
|
| It doesn't matter as long as the Mplus directory is part of your path environment variable. |

Hello,
I am conducting efa .All my dependent variables are categorical and I am using WLSMV estimator.My question is: should I rely on RMSEA or SRMR since RMSEA is 0,08 and SRMR is 0,03 for 3 factors? |
|

|
| You should also get at least chi-square and with the new rotations other fit statistics. As always in EFA, besides fit statistics, theory behind the number of factors for which the items were developed is a good guide. |

Hi Linda,
According theory 3 factors are enough. However, Chi-Square p-value for 3factors is 0.00. Moreover, I am not sure about Chi-S. since Mplus gives some notes:* The chi-square value for MLM, MLMV, MLR, ULSMV, WLSM and WLSMV cannot be used
for chi-square difference tests. MLM, MLR and WLSM chi-square difference
testing is described in the Mplus Technical Appendices at www.statmodel.com.
See chi-square difference testing in the index of the Mplus User's Guide.
** The degrees of freedom for MLMV, ULSMV and WLSMV are estimated according to
a formula given in the Mplus Technical Appendices at www.statmodel.com.
See degrees of freedom in the index of the Mplus User's Guide.
Are p-values from Chi-S. are still reliable?

|
| Yes, the p-values for all chi-square test statistics are reliable. |
