How to quantify the strength of factors in a contagion phenomena? — Fakhteh Ghanbarnejad, Martin Gerlach, Jose M. Miotto, and •Eduardo G. Altmann — Max Planck Institute for the Physics of Complex Systems, Dresden

Different factors contribute to the spreading of a process through a population. For instance, the adoption of an innovation may depend on factors such as peer pressure, agent specific believes, and the intrinsic fitness of the innovation. In this talk we (i) introduce a measure of the contribution of a factor to the overall spreading; (ii) show how this measure depends on the spreading dynamics (e.g., Bass or Threshold) and network topology; and (iii) propose methods to estimate the strength of factors from data.
