ABSTRACT We develop a functional conditional autoregressive (CAR) model for spatially correlated data for which functions are collected on areal units of a lattice. Our model performs functional response regression while accounting for spatial correlations with potentially nonseparable and nonstationary covariance structure, in both the space and functional domains. We show theoretically that our construction leads to a CAR model at each functional location, with spatial covariance parameters… 

Unified Principal Component Analysis for Sparse and Dense Functional Data under Spatial Dependency

This work considers spatially dependent functional data collected under a geostatistics setting, where spatial locations are irregular and random, and proposes a new functional principal component analysis method that borrows information from neighboring functions.

A robust spatial autoregressive scalar-on-function regression with t-distribution

A robust spatial autoregressive scalar-on-function regression is proposed by incorporating a spatial autOREgressive parameter and a spatial weight matrix into the SoFR to accommodate spatial dependencies among individuals.

An Efficient Nonparametric Estimate for Spatially Correlated Functional Data

The proposed weighted kernel smoothing estimate of the mean function that leverages the spatial and temporal correlation improves estimation and prediction in the presence of sparse observations, and therefore is advantageous to biomedical applications that utilize markers to identify features intrinsic to a particular disease at multiple interdependent sites within an organ.

Bayesian functional graphical models

The Bayesian functional graphical model can efficiently reconstruct the functionally-evolving graphical models by accounting for within-function correlations and borrowing strength across functional positions so contiguous locations are encouraged but not forced to have similar graph structure and edge strength.

Spatial homogeneity learning for spatially correlated functional data with application to COVID-19 Growth rate curves.

We study the spatial heterogeneity effect on regional COVID-19 pandemic timing and severity by analyzing the COVID-19 growth rate curves in the United States. We propose a geographically detailed

Topics in functional data analysis and machine learning predictive inference

A general framework and fully nonparametric estimation methods for spatial functional data collected under a geostatistics setting, where locations are sampled from a spatial point process and a random function is discretely observed at each location and contaminated with a functional nugget effect and measurement errors.

Recent developments in complex and spatially correlated functional data

The functional data approach offers a new paradigm of data analysis, where the continuous processes or random fields are considered as a single entity, and is considered to be very valuable in the context of big data.

Bayesian analysis of longitudinal and multidimensional functional data.

This article proposes a computationally efficient nonparametric Bayesian method to simultaneously smooth observed data, estimate conditional functional means and functional covariance surfaces, and conduct an implicit learning experiment in children with autism spectrum disorder.

Quantile Functional Regression using Quantlets

In this paper, we develop a quantile functional regression modeling framework that models the distribution of a set of common repeated observations from a subject through the quantile function, which

We propose an extensive framework for additive regression models for correlated functional responses, allowing for multiple partially nested or crossed functional random effects with flexible

Reduced Rank Mixed Effects Models for Spatially Correlated Hierarchical Functional Data

This work proposes a general framework of functional mixed effects model for within-unit and within-subunit variations are modeled through two separate sets of principal components; the subunit level functions are allowed to be correlated.

Robust, Adaptive Functional Regression in Functional Mixed Model Framework

This article introduces a new Bayesian method, robust functional mixed models (R-FMM), for performing robust functional regression within the general functional mixed model framework, which includes multiple continuous or categorical predictors and random effect functions accommodating potential between-function correlation induced by the experimental design.

Fast methods for spatially correlated multilevel functional data.

This work proposes a new methodological framework for the analysis of hierarchical functional data when the functions at the lowest level of the hierarchy are correlated, which leads to a computational algorithm that is orders of magnitude more efficient than its closest competitor.

A close look at the spatial structure implied by the CAR and SAR models

Wavelet‐based functional mixed models

New methodology is presented that generalizes the linear mixed model to the functional mixed model framework, with model fitting done by using a Bayesian wavelet-based approach, which is flexible, allowing functions of arbitrary form and the full range of fixed effects structures and between-curve covariance structures that are available in the Mixed model framework.

Statistics for spatial functional data: some recent contributions

The three classic types of spatial data structures (geostatistical data, point patterns, and areal data) can be combined with functional data as it is shown in the examples of each situation provided here.


This application aims to carry out inference on gradients of a temporal process in the authors' data set of monthly county level asthma hospitalization rates in the state of California, while at the same time accounting for spatial similarities of the temporal process across neighboring counties.

New methods to analyze data from an experiment using rodent models to investigate the role of p27, an important cell‐cycle mediator, in early colon carcinogenesis are presented and suggest the existence of significant crypt signaling.
