Detecting interaction networks in the human microbiome with conditional Granger causality
Fig 3
Frequency with which strong coefficients appear at different time-lags for interspecific interactions (left column) and for intraspecific interactions (right column).
Coefficients are shown for the gut, left-hand, right-hand and tongue. For each panel, the negative axis reflects time-lags with negative coefficients, while the positive axis reflects time-lags with positive coefficients. Pie-charts adjacent to each panel show the fraction of coefficients that are positive (blue) versus negative (orange).
