Parsimony is also a factor in statistics: in general, mathematic models with the smallest number of parameters are preferred as each parameter introduced into the model adds some uncertainty to it. Another way to say this is that the correct explanation or solution is usually the simplest. of maximum parsimony on networks, “hardwired” and “softwired,” and examine the complexity of computing them given a network topology and a character.

Parsimony, or the "principle of parsimony", is a method for selecting between equally valid hypotheses based on the complexity of each. As a logical principle, Occam's razor would demand that scientists accept the simplest possible theoretical explanation for existing data. The ultimate goal of scientific research is to generate theories to explain and predict behavior.
