Hello,

I am running a mediation analysis with two parallel mediators which are both latent variables. I am attempting to run 1000 bootstraps on the mediation to get bootstrapped confidence intervals for the direct, indirect and total effects. However, this bootstrapping has already been running for several weeks and looks like it will take several more.

I've read that 1000 bootstraps should be run as a minimum so I'm not sure reducing the number of bootstraps is an option.

I wondered whether there are any alternatives to bootstrapping which may run faster? E.g. is it acceptable to use robust standard errors instead?

Thanks,
Anna
