A robust approach for generalized linear models based on maximum Lq-likelihood procedure
Felipe Osorio, Manuel Galea, Patricia Gimenez
In this paper we propose a procedure for robust estimation in the context of generalized linear models based on the maximum Lq-likelihood method. Alongside this, an estimation algo…
