From: TINNiK: inference of the tree of blobs of a species network under the coalescent model
The TINNiK tree of blobs for fixed \(\alpha =10^{-4}\) and various \(\beta \) for a simulated sample of \(n = 1000\) gene trees for \({\mathcal {N}}^+\) with \(k=0.5\) (high ILS). Decreasing \(\beta \) results in less resolution in the tree of blobs. From left to right: (top) only the A- and C- groups are correct; all blobs except the B-blob are correct; (bottom) the TINNiK tree of blobs is correct for any \(\beta \in [10^{-34}, 10^{-9}]\); the D-group lacks sufficient resolution. For even smaller \(\beta \) the TINNiK tree of blobs degrades to a star tree
