number of iteration of bootstrapping for estimating SE of the indirect effect*

[Nesma Lotfy]

i want to know the suitable number of iteration of bootstrapping for estimating SE of the indirect effect

Nesma,

You could use my -bssize- command which calculates an "optimal" number of bootstrap replications to use, where the term optimal is defined in the accompanying Stata Journal article.

Type in

findit bssize

to find links to the SJ article and to install the command.

Nesma:
Efron B, Tibshirani RJ.An Introduction to the Bootstrap. New York: Chapman & Hall/CRC, 1993:47 recommends a range between 25 and 200 bootstrap replication for standard errors (200 replications are usually performed)
