[Mediation-information] Nonparametric Bootstrap

[Lawrence Ngo]

Dear Dr. Imai,

Thanks so much for putting together this useful mediation package. I have
been having an issue re-running a nonparametric bootstrap mediation
analysis. Comparing notes from the old and new analysis that I am doing on
the same data (and both using 10000 simulations), it looks like the
confidence intervals and p-values are different across the two analyses. I
am fairly confident that nothing has changed in my data, since all of the
parameter estimates are identical across old and new.

Do you have any insight on why this may be the case? I ran the old analysis
around 6 months ago. Thanks in advance for you help!

Best,
Lawrence
