rezids

Rezids is a term with no single, widely recognized definition in standard reference works. Its meaning depends on context and can refer to residual concepts or function as a proper noun in niche domains.

Generally, rezids may be used informally to denote residuals—portions left over after a calculation, process, or measurement. In statistics, residuals are the differences between observed data and model predictions; “rezids” is not an official term, but may appear in informal notes or software documentation.

In medicine, residual disease or tumor burden is used to describe disease that remains after therapy; some writers might abbreviate this informally as rezids in notes or discussions, but this usage is not standardized.

Etymology and usage vary; the form likely derives from resid- (Latin residere, to remain) with a plural suffix, but there is no canonical definition associated with the term.

Fictional or local uses may also occur, but such usages are not widely documented in authoritative sources. See also: residual, residue, residuum.
