Hello all, I'm very new to Mplus and the SEM world as a whole. I'm hoping the community could provide some references and direction. I'm interested forming a path model using composite indicators, but I can't find any information in the Mplus Users Guide regarding the syntax needed to eliminate the disturbance term in the composite variable. I'd appreciate any help! Thanks in advance. |

Have a look at our slides in the Topic 1 handout on our website. Towards the end you will find how to specify formative/composite indicators. You fix the residual variance to zero (f@0) and fix one slope to one (f ON x1@1). |

Assistance requested with persistent error. I am working with a model employing composite variables. Regardless of how I structure the model, I get this error every time. THE MODEL ESTIMATION TERMINATED NORMALLY THE CHI-SQUARE COULD NOT BE COMPUTED. THE CORRECTION FACTOR IS NEGATIVE. I cannot find anything in the guide book or online to suggest how I might address this problem. Any and all suggestions greatly appreciated. |
