Zac had learned to be decisive in Manyvifs. He did not ask why she came to him. He took the trunk and promised to put its pieces back together. It was a particular kind of promise: not to find the brother, perhaps, but to return the story whole.

We systematically searched Web of Science (2000–2024) for articles containing “multicollinearity” and “VIF” in the title/abstract and that reported regression results on ecological data. Inclusion criteria: (i) ≥ 30 predictors, (ii) VIF values reported or recoverable, (iii) full‑text available. This yielded studies (total N ≈ 1.4 M). For each, we extracted the proportion of predictors with VIF > 5 and VIF > 10, and the authors’ reported handling (e.g., variable removal, PCA). zac wild manyvifs
