Statistics - Magic or Math?
I used to hate statistics. Like many of you I first learned how to assess statistical significance through a variety of seemingly arbitrary formulas handed to me in Statistics 215. Sure I could calculate an answer, but I might as well have been attending Hogwart’s School of Witchcraft and Wizardry ; I saw no reason why any such formula should give a decree as to why certain things should be con...
متن کاملIdeological parsimony
The theoretical virtue of parsimony values the minimizing of theoretical commitments, but theoretical commitments come in two kinds: ontological and ideological. While the ontological commitments of a theory are the entities it posits, a theory’s ideological commitments are the primitive concepts it employs. Here, I show how we can extend the distinction between quantitative and qualitative par...
متن کاملUniversal Grammar, statistics or both?
Recent demonstrations of statistical learning in infants have reinvigorated the innateness versus learning debate in language acquisition. This article addresses these issues from both computational and developmental perspectives. First, I argue that statistical learning using transitional probabilities cannot reliably segment words when scaled to a realistic setting (e.g. child-directed Englis...
متن کاملDetecting community structure: From parsimony to weighted parsimony
Community detection has attracted a great deal of attention in recent years. A parsimony criterion for detecting this structure means that as minimal as possible number of inserted and deleted edges is needed when we make the network considered become a disjoint union of cliques. However, many small groups of nodes are obtained by directly using this criterion to some networks especially for sp...
متن کاملParsimony and explanatory power
Parsimony can be related to explanatory power, either by noting that each additional requirement for a separate origin of a feature reduces the number of observed similarities that can be explained as inheritance from a common ancestor; or else by applying Popper s formula for explanatory power together with the fact that parsimony yields maximum likelihood trees under No Common Mechanism (NCM)...
