Quick question, I hope. Anyway to bootstrap the standardized factor loadings? The unstandardized are great, but we really report the standardized more often. So, I was wondering if there is any way to perform this type of test. Thanks

Not at this time.

is it possible to get bootstrap results for the 90% confidence intervall? Thanks.

No, there is no option for this.

Hi Linda,

in brief my task: I've a moderated mediation model with observ. var. only which has only n=46 and therefor low power. I wanted to use a 90% bcbootstrap. Can you suggest another idea? Second question: is the model result also generated by the bootstrap sample e.g. estimator for path b or only the confidence intervalls and the estimator in that section?

thanks a lot.

We will add 90% bootstrap in the future but for now, I have no suggestions. Only standard errors and confidence intervals are bootstrapped not parameter estimates.

My reviewer asked me to use a bootstrapping to test my indirect effects in addition to the DELTA method. My sample size is small (140). I have missing cases so I have been using MLR in my path analysis. Bootstrapping is not available with MLR. I am using Mplus 6.2. I was wondring if it was available in the later versions or there is some other reason why the bootstrapping won't work with MLR. Is it acceptable to delete the missing values and then use ML with the bias-corrected bootstrap? The data does not seem to violate the normality assumption.

You can only use BOOTSTRAP wit ML and not MLR etc. because BOOTSTRAP affects the standard errors not the parameter estimates. The parameter estimates for ML, MLR, etc. are exactly the same. It is only the standard errors that differ. So use ML.

Using the commands for bootstrapping in the users' guide, I got everything I wanted except for the the Standard errors of the standardized path coefficients (direct effects). All I have is a column entitled "StdYX Estimate" with the standardized path coefficients. I am asked about the effect size. I can thus provide the standardized path coefficients but no SE from the bootstrapped results. How can I ask Mplus to give me the SE for those?
