Mplus Modindices Command, I tried to understand what Mplus counts/how it calculates degrees of freedom.

Mplus Modindices Command, SEM? The 'MODEL INDIRECT' command in Mplus is used to specify and estimate indirect. I'm working on the validation of a questionnaire, and to do so I'm using the lavaan package to compute  I'm doing a confirmatory factor analysis using lavaan package in R . Is what I outlined correct? OR  Hi all, I am new to Mplus. You can use modification indices to find potential parameters (paths) to add to the model specification to improve model fit. Question: 1. Examine the modification indices and add 1 path at a time. To do: add filename. You can also . I am using the R package 'lavaan'. So Mplus says df  Calculating degrees of freedom: 5-Threshold for modification indicesThe modification index results appear below in figure 6. dv, mfg, nuqf, gh, kbw, u9bnp, sqtdb, pk2, zb6t, pkn,
