Distrubution of Est./S.E. in WLS, WLS... PreviousNext

When indicators are all categorical or part of indicators are categorical, the estimators can be used in Mplus are WLS, WLSM, and WLSMV. In output there is Est./S.E. for each estimate. My question is what is (asymptotic) distribution of Est./S.E.? Can it be treated as standard normal or students t-distribution? If not, how to use that value to judge the significance of the estimate?

Could you give me any reference?

Standard normal. See the following reference:

I am building a manifest path model with categorical variables using WLSMV, the variables had been skewed.

Can I derive a one-tailed p-value from the two-tailed p-values given in the MODEL RESULT section by deviding the two-tailed p-value through 2?

Thanks a lot in advance.

You will need to look up the value of the ratio of the parameter estimate to its standard error in a z-table to obtain the p-value.
