Author manuscript; accessible in PMC 2015 January 08.Miller and KissPageThis combined with the perform within the most important text shows that if Ik and Sk are initially kindependent (equivalently, the pairs closure holds), then the basic pairwise model reduces for the compact pairwise model. We're now prepared to derive the EBCM equations from the compact pairwise model. B.2.2. Deriving EBCM model from compact pairwise model We title= cas.12979 now derive the EBCM model in the compact pairwise model. We later derive the compact pairwise model in the EBCM model. We begin our derivation with the observation that (for all k) [k] = ?k Sk [Sk]. So . We define . If we define ()/ (). We have We return for the equations .E the pair plays this part.B.two. Simplifications of fundamental pairwise modelWe begin by showing that the basic pairwise model may be reduced for the compact pairwise model, and that in turn, that is equivalent for the EBCM model. B.two.1. Deriving compact pairwise model from standard pairwise model We presented two pairwise models. In each, we assumed the triples closure: Nothing we know about one partner of a susceptible individual u provides any information and facts about a different partner of u. We showed that the first reduces to the second if we assume that offered susceptible u nothing we know about its degree gives any details about no matter whether its companion v is infected or susceptible. Mathematically, this states that Ik = [SkI]/k[Sk] and Sk = [SkS]/k[Sk] are independent of k. The combination of these two assumptions offers us the pairs closure. So under the pairs closure, we count on the compact pairwise model to hold.Math Model Nat Phenom. Author manuscript; readily available in PMC 2015 January 08.Miller and KissPageOur derivation from the EBCM model was primarily based on the pairs closure. So we count on some change of variables to show that it really is equivalent to the compact pairwise model.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptIt was previously noted [12] that if we make the generic assumption that where [AkB] represents the number of partnerships among people of status A obtaining k partners and people of status B, then a pairwise strategy might be utilised to derive an early version with the EBCM model [47]. In general, we anticipate this assumption to fail if A is either I or R. On the other hand, within the distinct case where status A is susceptible, the assumption is consistent: No matter the degree of a person, it has no impact around the status of its neighbors so extended since it remains susceptible.
