What are theories of causation?

What are accident causation theories?

What is the modern accident causation model?
The Accident Causation Model (or “Swiss Cheese Model “) is a theoretical model that illustrates how accidents occur in organisations. It postulates that the typical accident occurs because several (human) errors have occurred at all levels in the organisational hierarchy in a way that made such accident inavoidable.
What are the models of causation?
Causal models are mathematical models representing causal relationships within an individual system or population. They facilitate inferences about causal relationships from statistical data. They can teach us a good deal about the epistemology of causation, and about the relationship between causation and probability.
