SPSS / logistic regression

I have performed a logistic regression using 5 different variables in a nested approach.

Does this mean I have also performed mediation or do I need to that separately?

I am very new to logistic regression ... and within a learning process.
Mediation analysis is a completely different thing, which by itself is irrelevant to your estimator. You can look here to get a sense of it.


Less is more. Stay pure. Stay poor.
You should have context knowledge of why or why not mediation may be present. An analyst should not just go looking for it without reason. :)
