Domain-specific¶
- Smearing retransformation
- Smearing retransformation corrects the bias that arises because exponentiating a predicted log mean does not generally equal the conditional mean on the original scale.
- The entry records a descriptive analytical identity; practical use requires the governing domain's evidence, standards, and safety obligations.
Mechanisms¶
- Log-Log Regression Fit
- Log-space fitting is simple and stabilizes variance but introduces a back-transformation bias in `a`.
This sourceShows that returning transformed-scale predictions to the original scale can introduce retransformation bias.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 3 citations of this work carries a 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.
