Moderator Variable
Moderator Variable : Disaster Management. (Syn: qualifier variable) In a study of a possible causal factor and an outcome, a moderator variable is a third variable exhibiting statistical interaction by virtue of its being antecedent or intermediate in the causal process under stiffly. If it is antecedent, it is termed a conditional moderator variable or effect modifier; if it is intermediate, it is a contingent moderator variable. [Last, 1983: A Dictionary of Epidemiology]
