A Causal Inference is a logical inference based on causal relationships.



  • (Wikipedia, 2020) ⇒ Retrieved:2020-12-15.
    • Causal inference is the process of drawing a conclusion about a causal connection based on the conditions of the occurrence of an effect. The main difference between causal inference and inference of association is that the former analyzes the response of the effect variable when the cause is changed. The science of why things occur is called etiology. Causal inference is an example of causal reasoning.

    • QUOTE: … it is important to understand the achievements that causal inference has tallied thus far. We will explore the way that it has transformed the thinking of scientists in almost every data-informed discipline and how it is about to change our lives.
    • The new science addresses seemingly straightforward questions like these:
      • How effective is a given treatment in preventing a disease?
      • Did the new tax law cause our sales to go up, or was it our advertising campaign?
      • What is the health-care cost attributable to obesity?
      • Can hiring records prove an employer is guilty of a policy of sex discrimination?
      • I’m about to quit my job. Should I?
    • These questions have in common a concern with cause-and-effect relationships, recognizable through words such as “preventing,” “cause,” “attributable to,” “policy,” and “should I.” Such words are common in everyday language, and our society constantly demands answers to such questions. Yet, until very recently, science gave us no means even to articulate, let alone answer, them.
