Hello,
I am trying to conduct a sensitivity analysis for a simple mediation model, that was conducted in SPSS using the PROCESS Macro by Hayes (Model 4).
I have the following information:
- Sample Size N = 1081
- α = .05
- 1−β = .90
How can I find out, which size the indirect effect has, that can be detected with these settings? Which program can I use for this?
Do I have to know the Effects of path a and path b to be able to conduct the sensitivity analysis?
Figure is taken from: The Englisch Wikipedia site "Mediation (statistics)"
See my attached paper where I performed a univariate sensitivity analysis. It tells you what to do there :)
Thank you for your answer, but I am trying to find out the effect size that can be detected with a simple mediation analysis when the sample size, α and power are given.
