Abstract

Summary: We consider the problem of selecting grouped variables (factors) for accurate prediction in regression. Such a problem arises naturally in many practical situations with the multifactor analysis-of-variance problem as the most important and well-known example. Instead of selecting factors by stepwise backward elimination, we focus on the accuracy of estimation and consider extensions of the lasso, the LARS algorithm and the non-negative garrotte for factor selection. The lasso, the LARS algorithm and the non-negative garrotte are recently proposed regression methods that can be used to select individual variables. We study and propose efficient algorithms for the extensions of these methods for factor selection and show that these extensions give superior performance to the traditional stepwise backward elimination method in factor selection problems. We study the similarities and the differences between these methods. Simulations and real examples are used to illustrate the methods.

  • New filtering formulations that organize streamlines into groups and seek the minimum number of bundles using Group Lasso significantly improve anatomical accuracy of the connectome.

    “This prior knowledge helps resolve some of the ambiguities present in the data and, as a consequence, allows significant improvement of the anatomical accuracy of the connectome (Ocampo-Pineda et al., 2021; Schiavi et al., 2020a).”

    From Quantitative mapping of the brain’s structural connectivity using diffusion MRI tractography: A review (2022) · cites this paper as Yuan and Lin, 2006

    Section 2 (Group lasso; page not available) says group lasso selects groups of variables and encourages sparsity at the factor level. The paper does not address streamline filtering, bundles, connectomes, or improved anatomical accuracy; those application and outcome claims are unsupported by this source. (LLM, conf=0.84)

  • Group Lasso helps in selecting physically meaningful groups of attributes in data science models.

    “Group Lasso helps in selecting physically meaningful groups of attributes in the data science models, and various extensions of group Lasso have been explored for handling different types of domain characteristics, e.g., overlapping group Lasso [63], tree-guided group Lasso [64], and sparse group Lasso [65].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
