Random Intercept EFA (RI-EFA) |

I am working with a measure of Big Five personality traits. The indicators are on an ordinal scale, so categorical in MPLUS. Following the steps outlined by Aichholzer, 2014, I am attempting an RI-EFA to help adjust for response bias. The author includes the MPLUS syntax in the manuscript which I followed. When I run a straight EFA, CFA, or ESEM - I have no problems. But in this RI-EFA, I am getting an error message and I am not getting model fit statistics. Can you help me identify what I am doing wrong? The error is: "THE MODEL ESTIMATION TERMINATED NORMALLY THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES COULD NOT BE COMPUTED. THE MODEL MAY NOT BE IDENTIFIED. CHECK YOUR MODEL. PROBLEM INVOLVING THE FOLLOWING PARAMETER: Parameter 716, F5 BY FFPIC81 THE CONDITION NUMBER IS -0.928D-18." I can send syntax in a following post |

Your statement RI BY FFPIC01 FFPIC02 FFPIC03 FFPIC04 [...rest of variables...] FFPIC75 FFPIC77 FFPIC78 FFPIC79 FFPIC80 FFPIC81 FFPIC82 FFPIC83@1; does not fix all loadings at 1, only the last one. You have to either use a list or repeat @1. We ask that postings be limited to one window. |

Thank you! I will change my syntax accordingly. My apologies for posting in two windows. I will be sure to post in only one in the future. |
