Functional Group Bridge for Simultaneous Regression and Support Estimation

  title={Functional Group Bridge for Simultaneous Regression and Support Estimation},
  author={Zhengjia Wang and John F. Magnotti and Michael S. Beauchamp and Meng Li},
  journal={arXiv: Methodology},
There is a wide variety of applications where the unknown nonparametric functions are locally sparse, and the support of a function as well as the function itself is of primary interest. In the function-on-scalar setting, while there has been a rich literature on function estimation, the study of recovering the function support is limited. In this article, we consider the function-on-scalar mixed effect model and propose a weighted group bridge approach for simultaneous function estimation and… Expand

Equivalence of Convergence Rates of Posterior Distributions and Bayes Estimators for Functions and Nonparametric Functionals
We study the posterior contraction rates of a Bayesian method with Gaussian process priors in nonparametric regression and its plug-in property for differential operators. For a general class ofExpand


Functional sparsity: global versus local
We consider the model selection problem in nonparametric regression. The notion of functional sparsity is a generalization of parameter sparsity in parametric models. In particular, two differentExpand
Variable Selection in Function-on-Scalar Regression.
This work adapts techniques from generalized least squares to account for residual covariance by "pre-whitening" using an estimate of the covariance matrix, and develops an iterative algorithm that alternately updates the spline coefficients and covariance. Expand
Bridge regression: Adaptivity and group selection
Abstract In high-dimensional regression problems regularization methods have been a popular choice to address variable selection and multicollinearity. In this paper we study bridge regression thatExpand
High-dimensional adaptive function-on-scalar regression
Applications of functional data with large numbers of predictors have grown precipitously in recent years, driven, in part, by rapid advances in genotyping technologies. Given the large numbers ofExpand
The adaptive group Lasso procedure works well with samples of moderate size and achieves the optimal rate of convergence in a nonparametric additive model of a conditional mean function that may be larger than the sample size but the number of nonzero additive components is "small" relative to the sample Size.

Functional Linear Model with Zero-value Coefficient Function at Sub-regions.
The refined estimator achieves superior numerical performance in practice and achieves the Oracle property; it identifies the null region with probability tending to 1, and it achieves the same asymptotic normality for the estimated coefficient function on the non-null region as the functional linear model estimator when theNon- null region is known.

Variable Selection via Nonconcave Penalized Likelihood and its Oracle Properties
Variable selection is fundamental to high-dimensional statistical modeling, including nonparametric regression. Many approaches in use are stepwise selection procedures, which can be computationallyExpand
Locally Sparse Estimator for Functional Linear Regression Models
ABSTRACT A new locally sparse (i.e., zero on some subregions) estimator for coefficient functions in functional linear regression models is developed based on a novel functional regularizationExpand
Asymptotic properties of bridge estimators in sparse high-dimensional regression models
We study the asymptotic properties of bridge estimators in sparse, high-dimensional, linear regression models when the number of covariates may increase to infinity with the sample size. We areExpand
Optimal estimation of the mean function based on discretely sampled functional data: Phase transition
The problem of estimating the mean of random functions based on discretely sampled data arises naturally in functional data analysis. In this paper, we study optimal estimation of the mean functionExpand
