Poisson Random VariableMultiple Time SeriesWe investigate an association between a power-law relationship of constituents' flows (mean versus standard deviation) and their covariance matrix on a directed bipartite network. We propose a Poisson mixture model and a method to infer states of the ...
Notably, this result generalizes to positive and negative binomial distributions, which include Poisson distributions. 2 Power-laws or scale-free distributions, despite their name, are not invariant under subsampling. Namely, if P(s) follows a power-law distribution, then Psub(s) is not a ...
Once this collection of values is obtained, for a given density (total number of trips Ttrips generated in a given timespan τ) the allocation of trips to each intersection pair ij reads <tij> = Ttrips pij with tij an integer random variable following a Poisson distribution. We have ...

[7] have recently improved these results for small and moderate values of α by providing a 2α−1B̃α-approximation algorithm, where B̃α is the generalized Bell number and corresponds to the α-th (fractional) moment of Poisson random variable with parameter 1. Notice that the ...
Gypsum has been favoured for many years as a representative concrete model material, especially for analyses in the elastic regime, due to its high workability, low Poisson’s ratio and linear stress–strain relationship. However, its stress–strain response is substantially different to that of ...
The traffic flow is input into the network through link origins, and the traffic flow subjects to Poisson distribution. In order to test the effectiveness of the proposed method under different environments, four kinds of OD input data are employed: OD1, OD2, OD3, and OD4. OD1, OD2, ...
Letfor all. Therandom variable is to be the stopping time of thenth update at a given sitej. We set We will denote the set of all points in space-time at which an update occurs as The idea is to construct the IPS inductively, update by update. This approach poses a technical challen...
Bern(λ) random assignment of each point in the Update set to be either a "P" update or an "I " update is a random coloring of the family of independent Poisson processes of updates at each vertex of the lattice. Hence the rescaled trajectory which completes the proof. (ξλt )t≥0...
