Description: A framework for matrix completion and regression on
        response matrices with missing values. The model estimates
        missing entries using any combination of intercepts, row and
        column covariates, and a low-rank matrix approximation. It
        applies Lasso penalties on the covariates and a nuclear norm
        penalty on the low-rank component. It also adjusts for
        correlation within the rows and columns of the target matrix
        using similarity matrices. The framework is described in Fouda,
        Labbe and Oualkacha (2026) <doi:10.48550/arXiv.2606.26325>.
