Figure 5From: Digital traces of brain drain: developers during the Russian invasion of UkraineThe normalized Shannon entropy of the Russian software developer collaboration network when removing leavers (in red) and a random subset of developers of the same size (1000 times, distribution in grey). Higher scores indicate greater levels of fragmentation. The Z-score compares the targeted removal with random removal, and indicates that leavers play a distinguished role in overall network connectivityBack to article page
