Article is thinly veiled self promotion of an obscure statistical heuristic, written by sockpuppet account of the creator of the heuristic, Marcos Lopez de Prado. Topic does not rise to notability standards. Shabbychef (talk) 05:53, 26 June 2026 (UTC)
Article edited a few times by Dsr02014, a sockpuppet account set up to edit and curate the page on Deflated Sharpe Ratio, another obscure technique created by the same author, but then principally edited by user Cpcv2026 (Presumably standing for "Combinatorial Purged Cross Validation 2026". Said user pretends to be a student on their talk page, then crafts a very detailed page about one obscure statistical practice nobody uses, then disappears. This is just flagrant self-promotion. — Preceding unsigned comment added by Shabbychef (talk • contribs) 05:57, 26 June 2026 (UTC)
