流行病最终规模分布的计算

Computation of epidemic final size distributions

Andrew J. Black, J. V. Ross

摘要:

我们开发了一种新的方法,有效地计算流行病的最终规模分布的广泛的一类马尔可夫模型。我们利用一个特殊的表示的随机流行病过程,推导出一种方法,这是计算效率和数值稳定。我们提出的算法在物理上也是透明的,因此允许我们将这种方法从基本的SIR模型扩展到具有阶段型感染期和另一个免疫力减弱的模型。基本理论适用于许多马尔可夫模型,我们希望有效地计算命中概率。

英文摘要:

We develop a new methodology for the efficient computation of epidemic final size distributions for a broad class of Markovian models. We exploit a particular representation of the stochastic epidemic process to derive a method which is both computationally efficient and numerically stable. The algorithms we present are also physically transparent and so allow us to extend this method from the basic SIR model to a model with a phase-type infectious period and another with waning immunity. The underlying theory is applicable to many Markovian models where we wish to efficiently calculate hitting probabilities.
