I'm trying to fit a saturated model where the variable, 'manifests', includes all of the variables in the model. The non-saturated structural model runs fine, but I get an error when I fit the saturated model:
Error: The job for model 'Saturated Model2' exited abnormally with the error message: Expected covariance matrix is not positive-definite in data row 79 at iteration 0.
I have tried fiddling with the starting values, but to no avail. By the way, I know that all=TRUE is being deprecated, and I have written the same code in a longer form without all=TRUE, but this was shorter, so I thought it'd be easier to post. Below is the model:
saturated_model <- mxModel(paste("Saturated Model"),
#Variances and Covariances
saturatedModel_run <- mxRun(saturated_model)
Any help would be greatly appreciated. Thanks!
