WebApr 10, 2024 · However, blockwise approaches such as the above-mentioned, and blockwise sparse regression proposed by Kim et al. [39], are not applicable in this setting due to the presence of the fusion penalty. The fusion penalty results in a problem that is not separable, posing a computational challenge to the optimisation problem via such … WebAs David pointed out, there is no difference between the two approaches and the final model will in both cases be the same, so there is no intrinsic need to do a blockwise regression, unless... georgia county indicator report
