Hi-- What distribution does Mplus use to test the significance of the variance of the latent slopes and interceptn in growth models? Thanks, Igor |
|
|
What's printed in the output for a single variance is simply the ratio of estimate to SE and the p-value is computed assuming that this has a normal distribution; this is the standard output. It is well known that this is not a great way to test variances. |

Thanks for the response. Any suggestions for a more sophisticated way to test the variances in Mplus? Thanks, Igor |

There are interesting references on this, but new methods have not yet been implemented in Mplus. See, e.g., the 2004 JRSS-B article by Crainiceanu-Ruppert and the 2001 Berkhof-Snijders article in JEBS. |
