Generalized nonparametric regression in reproducing kernel Hilbert spaces: Consistency and rates of convergence

Ioannis Kalogridis

We develop a comprehensive theory for regularized M-estimation in reproducing kernel Hilbert spaces. Under mild conditions on the loss we establish existence and measurability of t…

Penalized Spline M-Estimators for Discretely Sampled Functional Data: Existence and Asymptotics

Ioannis Kalogridis

Location estimation is a central problem in functional data analysis. In this paper, we investigate penalized spline estimators of location for discretely sampled functional data u…

Robust Functional Regression with Discretely Sampled Predictors

Ioannis Kalogridis, Stanislav Nagy

The functional linear model is an important extension of the classical regression model allowing for scalar responses to be modeled as functions of stochastic processes. Yet, despi…

Robust and Adaptive Functional Logistic Regression

Ioannis Kalogridis

We introduce and study a family of robust estimators for the functional logistic regression model whose robustness automatically adapts to the data thereby leading to estimators wi…

Robust thin-plate splines for multivariate spatial smoothing

Ioannis Kalogridis

We propose a novel family of multivariate robust smoothers based on the thin-plate (Sobolev) penalty that is particularly suitable for the analysis of spatial data. The proposed fa…

Robust and efficient estimation of nonparametric generalized linear models

Ioannis Kalogridis, Gerda Claeskens, Stefan Van Aelst

Generalized linear models are flexible tools for the analysis of diverse datasets, but the classical formulation requires that the parametric component is correctly specified and t…

Robust penalized spline estimation with difference penalties

Ioannis Kalogridis, Stefan Van Aelst

Penalized spline estimation with discrete difference penalties (P-splines) is a popular estimation method for semiparametric models, but the classical least-squares estimator is hi…

Robust optimal estimation of location from discretely sampled functional data

Ioannis Kalogridis, Stefan Van Aelst

Estimating location is a central problem in functional data analysis, yet most current estimation procedures either unrealistically assume completely observed trajectories or lack…

Asymptotics for M-type smoothing splines with non-smooth objective functions

Ioannis Kalogridis

M-type smoothing splines are a broad class of spline estimators that include the popular least-squares smoothing spline but also spline estimators that are less susceptible to outl…

Robust penalized estimators for functional linear regression

Ioannis Kalogridis, Stefan Van Aelst

Functional data analysis is a fast evolving branch of statistics. Estimation procedures for the popular functional linear model either suffer from lack of robustness or are computa…

M-type penalized splines with auxiliary scale estimation

Ioannis Kalogridis, Stefan Van Aelst

Penalized spline smoothing is a popular and flexible method of obtaining estimates in nonparametric regression but the classical least-squares criterion is highly susceptible to mo…

Robust functional regression based on principal components

Ioannis Kalogridis, Stefan Van Aelst

Functional data analysis is a fast evolving branch of modern statistics and the functional linear model has become popular in recent years. However, most estimation methods for thi…
