Dear all I have an error mesage « error message : the MLM estimator can not be used when data are incomplete » When i use the function sem(package lavaan) and when i fill the paramters estimator and missing estimator="MLM", missing="ml" i understand by this that i am not allowed to use estimator= ``mlm `` in parralle to the parameter missing
You understood correctly. Estimator 'MLM' (=ML estimation + Satorra-Bentler scaled test statistic) is only defined for complete data. The equivalent for incomplete data is the estimator 'MLR' (=ML estimation + Yuan-Bentler scaled test statistic).
