      Optimal testing for additivity in multiple nonparametric regression 

      Abramovich, F.; De Feis, I.; Sapatinas, Theofanis (2009)
      We consider the problem of testing for additivity in the standard multiple nonparametric regression model. We derive optimal (in the minimax sense) non- adaptive and adaptive hypothesis testing procedures for additivity ...
