parsimony, parsimonious The principle that the best statistical model among all satisfactory models is that with the fewest parameters. Hence, more generally, the principle which asserts that if it is possible to explain a phenomenon equally adequately in a number of different ways, then the simplest of explanations (in terms of the number of variables or propositions) should be selected.
