We introduce a user-friendly computational framework for implementing robust versions of structured regression methods. The framework allows robust regression with the L-2 criterion for additional structural constraints, without requiring complex tuning procedures. It can be used to identify heterogeneous subpopulations and can incorporate nonrobust structured regression solvers. We provide convergence guarantees for the framework and demonstrate its flexibility with examples.
We introduce a user-friendly computational framework for implementing robust versions of a wide variety of structured regression methods with the L-2 criterion. In addition to introducing an algorithm for performing L2E regression, our framework enables robust regression with the L-2 criterion for additional structural constraints, works without requiring complex tuning procedures on the precision parameter, can be used to identify heterogeneous subpopulations, and can incorporate readily available nonrobust structured regression solvers. We provide convergence guarantees for the framework and demonstrate its flexibility with some examples. for this article are available online.
