    The Alternating Direction Method of Multipliers for Sufficient Dimension Reduction by Sheng Ma, Qin Jiang, Zaiqiang Ku

    Published 2024-01-01
    “…The minimum average variance estimation (MAVE) method has proven to be an effective approach to sufficient dimension reduction. In this study, we apply the computationally efficient optimization algorithm named alternating direction method of multipliers (ADMM) to a particular approach (MAVE or minimum average variance estimation) to the problem of sufficient dimension reduction (SDR). …”

    Multivariate Analyses with Two-Step Dimension Reduction for an Association Study Between <sup>11</sup>C-Pittsburgh Compound B and Magnetic Resonance Imaging in Alzheimer’s Disease by Atsushi Kawaguchi, Fumio Yamashita

    Published 2025-01-01
    “…To study the relationship between Aβ deposition and brain structure, as determined using <sup>11</sup>C-Pittsburgh compound B (PiB) and magnetic resonance imaging (MRI), respectively, we developed a regression model with PiB and MRI data as the predictor and response variables, respectively, and proposed a regression method for studying the association between them based on a supervised sparse multivariate analysis with dimension reduction based on a composite paired basis function. …”

    Interpretability of Composite Indicators Based on Principal Components by Kris Boudt, Marco d’Errico, Hong Anh Luu, Rebecca Pietrelli

    Published 2022-01-01
    “…Principal component approaches are often used in the construction of composite indicators to summarize the information of input variables. The gain of dimension reduction comes at the cost of difficulties in interpretation, inaccurate targeting, and possible conflicts with the theoretical framework when the signs in the loading are not aligned with the expected direction of impact. …”
