Robust estimates in generalized partially linear single-index models

A natural generalization of the well known generalized linear models is to allow only for some of the predictors to be modeled linearly while others are modeled nonparametrically. However, this model can face the so called "curse of dimensionality" problem that can be solved by imposing a...
