Abstract(in English) In this paper, we applied Convergent Cross Mapping to estimate causal relations between multiple timeseries. We used a coupled logistic map to produce the multiple timeseries, and the Watts-Strogatz model as a network structure. For this network, we examined how the estimation accuracy of the causal relationship between each vertex changes with various rewiring probabilities. We also investigated the estimation accuracy of the causal relation depending on the existence of the community structure in the network. As a result, it was suggested that the difference in the network structure does not affect the estimation accuracy of the causal relation.
