I'm trying to compute the STDYX estimates for an observed path analysis by hand. The Mplus manual says SD(Y) is the model estimated standard deviation of Y. Is there a way to see this computed SD(Y) in the output?

Take the square root of the model estimated variance.

The residual variance?

Oh...I think you mean from the covariance matrix. But the STDYX estimates are a bit off when I do the calculation by hand. Is this normal, or is there something else to account for?

Where are the model-estimated variances located in Mplus output??

TECH4 or RESIDUAL.

You're a life saver! Thanks, Linda!! Can't wait on version 7.2!!
