Predictive accuracy of the three models. For each fold of the data, we show the predictive accuracy of the three models: naive, single-membership SBM and MMSBM. Each bar represents the average over 23 different network representations (as detailed in Fig. 3), which combine the variables that are more informative of players decisions (player’s decision at \(t-1\), market evolution at \(t-1\), outcome of decision at \(t-1\), expert consultation, advice consulted, average market trend over the 5 last/all rounds, market’s evolution/outcome before the previous round; see Additional file 1, Figs. 1–4)
