Least-angle regression
Algorithms AIMech:LeastAngleRegression DRAFT
Aliases: LARS
Regression that advances along directions equiangular to predictors most correlated with the residual.
Identity Notes & Concept Scope
RegressionAnalysis does not specify the equiangular active-predictor fitting path; distinguish this algorithm from the resulting regression model.
Claims & Grounded Evidence
1 Claim
Mechanism
#mechanism
The coefficient path moves in a direction equiangular to the active predictors until another predictor joins the active set.
⚠️ Curated Limitations & Negative Results
- This record supports method identity and the stated mechanism only; no universal performance or biological efficacy claim is curated.
- Proposed placement is an inference from the existing AIO hierarchy; maintainers must resolve task, algorithm and model scope before acceptance.
