- Idempotence
- … Schröder (1890–1905) systematized); idempotent matrices `P² = P` are projection operators onto subspaces, central to linear algebra and statistics (the hat matrix `H = X(XᵀX)⁻¹Xᵀ` projecting observed `y` onto fitted `ŷ` is idempotent, as Hoaglin and Welsch (1978) develop in their treatment of regression diagnostics).
This source(Explicit formulation of idempotent law: `a · a = a` and `a + a = a` in Boolean algebra; systematic treatment of idempotence as algebraic principle.)

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
