Reliability

Where calculation reliability stands

VoLCA is compared with results published by database producers, using the same source data and their impact factors.

Every impact category a publisher's table holds for the method families measured here is shown, the ones that disagree included, each with the verdict a release is held to. What does not agree is on this page for the same reason as what does: so that anyone can see where the engine stands.

366 drawn comparisons, 67 of which miss the agreement a release is held to. Every category a publisher's table holds is drawn, whether it agrees or not, and says which. Cells cover categories recorded across measured engines, within each database and collection. Gray cells distinguish recorded refusals from measurements not recorded. Colors identify databases only.
