  8. 8. Filtering model •  Expected chance that two countries edit the same article with size n, follows a multinomial distribution. < AB >= n(n−1)pA pB var(AB)= n(n−1)pA pB((6−4n)pA pB +(n−2)(pA + pB )+1)
  9. 9. Extracting significant links z-score =Σ ((empirical weight – expected weight) / standard deviation) •  Threshold: 5% pvalue with Bonferroni correction Significant weight = z-score - threshold
