中文摘要
我们提出了新的方法来分析生态,即捕食者-猎物,以及流行病数据。重点是在这种情况下,例如生态学中的相互作用参数,或在流行病研究的基本繁殖数估计的关键参数。这些参数分别控制着捕食者-猎物种群的规模和流行病的传播。在这两种情况下,出发点是新的特定模型,将确定性动力学纳入非齐次泊松或出生和死亡过程。此外,我们开发了一种估计方法,考虑到如何收集现场数据,特别是许多仪器的数量是很难或不可能测量。
英文摘要
We are proposing novel methods for analyzing ecological, namely predator-prey, as well as epidemic data. The focus is on estimating crucial parameters in such contexts, for example the interaction parameters in ecology, or the basic reproduction number in epidemic studies. These parameters control the size of predator-prey populations, respectively the spread of epidemics. In both contexts, the starting points are new specific models, incorporating deterministic dynamics into a non homogeneous Poisson or birth and death process. Further, we develop an estimation methodology that takes into account how field data are collected, in particular that many instrumental quantities are hard or impossible to measure.
