A mediator explains how or why two variables are related. A moderator affects the strength or direction of the relationship.
Although they sound similar, moderating variables are conceptually different from mediating (intermediate) variables. The difference is very subtle; Depending on your question,some variables can be both a moderator and a mediator[1]. Moderators answer the question “when?” or “under what conditions?
The mediate command allows both outcome and mediator variables to be continuous, binary, count, and nonnegative. The treatment may be binary, multivalued, or continuous. Models may be specified for the treatment and the mediator. This estimator relies on the SUTVA, unconfoundedness (conditional-...
Often researchers have a difficult time choosing the parameters and variables (like explanatory and response variables) that answer their aims and objectives in research study. The primary objective of any study is to determine whether there is a cause-and-effect relationship between variables. Therefo...
Use your subject-area knowledge to assess correlations and ask lots of questions: Do they make sense as causal relationships? Do they fit established theory? Can you find a mechanism for causation? Is there a direct link, or are mediator variables involved?
Example: Independent and dependent variables You design a study to test whether changes in room temperature have an effect on math test scores. Yourindependent variableis the temperature of the room. You vary the room temperature by making it cooler for half the participants, and warmer for the...

This chapter provides examples of the configuration steps that are used when using BPEL and Mediator to work with the Oracle CDC adapters. You should be familiar with the following before working with these examples: How to create J2CA connections. SeeConfiguring the JCA Configuration Files for th...
Modules can cooperate through a mediator or a public facade, hiding all private internals of the module to avoid its misuse, and giving public access only to certain pieces of functionality that meant to be public. Alternatively modules can communicate with each other by using messages. For exam...
