Mediation Analysis
Test how much of an independent variable's effect on the dependent variable is transmitted through a mediator variable. A complete mediation report with bootstrap confidence interval and Sobel test — the equivalent of SPSS Process/Hayes.
a, b, c, c' Paths
The total effect, the indirect path, and the direct effect remaining after controlling for M are each calculated separately.
Bootstrap Confidence Interval
The significance of the indirect effect (a×b) is tested with a 5,000-resample bootstrap 95% CI — the same logic as the Hayes/Process method.
Sobel Test
The classic Sobel z test is reported as additional verification.
