WebDec 1, 2024 · A clustering algorithm must never be informed about the location of such “problematic” points. Once the partition of the dataset is determined, they are excluded from the computation of the external cluster validity measures. In other words, it does not matter to which clusters the noise points are allocated. 3. The Python API Web43 minutes ago · We obtained similar results when: (1) using the greenwashing measure from clustering, suggesting that the greenwashing effect is robust to alternative measurement; (2) using a weekly (rather than daily) panel of estimation, suggesting that the greenwashing effect is also stable through the week; and (3) examining the individual …
