函数型数据分析的高斯过程:R语言的GPFDA程序包

Gaussian Process for Functional Data Analysis: The GPFDA Package for R

Evandro Konzen, Yafeng Cheng, Jian Qing Shi

摘要:

我们提出并描述了GPFDA包的R。该软件包提供了灵活的功能,用于处理功能数据的高斯过程回归(GPR)模型。可以对多变量函数数据、具有多维输入的函数数据以及不可分离和/或非平稳协方差结构进行建模。此外,该软件包还拟合函数回归模型,其中均值函数取决于标量和/或函数协变量,协方差结构由GPR模型建模。本文介绍了GPFDA在均值函数和协方差函数规范方面的通用性,并通过可重复的数值例子说明了一些模型的估计和预测的实现。

英文摘要:

We present and describe the GPFDA package for R. The package provides flexible functionalities for dealing with Gaussian process regression (GPR) models for functional data. Multivariate functional data, functional data with multidimensional inputs, and nonseparable and/or nonstationary covariance structures can be modeled. In addition, the package fits functional regression models where the mean function depends on scalar and/or functional covariates and the covariance structure is modeled by a GPR model. In this paper, we present the versatility of GPFDA with respect to mean function and covariance function specifications and illustrate the implementation of estimation and prediction of some models through reproducible numerical examples.
