Estimation of the Spatial Weighting Matrix for Spatiotemporal Data under the Presence of Structural Breaks

  title={Estimation of the Spatial Weighting Matrix for Spatiotemporal Data under the Presence of Structural Breaks},
  author={Philipp Otto and Rick Steinert},
  journal={arXiv: Computation},
In this paper, we propose a two-step lasso estimation approach to estimate the full spatial weights matrix of spatiotemporal autoregressive models. In addition, we allow for an unknown number of structural breaks in the local means of each spatial locations. The proposed approach jointly estimates the spatial dependence, all structural breaks, and the local mean levels. In addition, it is easy to compute the suggested estimators, because of a convex objective function resulting from a slight…

Dynamic Spatial Autoregressive Models with Time-Varying Spatial Weighting Matrices
We propose a new spatio-temporal model with time-varying spatial weighting matrices. We allow for a general parameterization of the spatial matrix, such as: (i) a function of the inverse distances
Estimation of the spatial weighting matrix for regular lattice data—An adaptive lasso approach with cross‐sectional resampling
Spatial autoregressive models typically rely on the assumption that the spatial dependence structure is known in advance and is represented by a deterministic spatial weights matrix, although it is
spGARCH: An R-Package for Spatial and Spatiotemporal ARCH and GARCH models
It is shown how the proposed spatial ARCH models can be simulated and summarized the variety of spatial models, which can be estimated by the estimation functions provided in the package, and applies all procedures to a real-data example.
Spatial Statistics, or How to Extract Knowledge from Data
This paper describes classical modeling approaches in geostatistics and spatial econometrics, and shows how large spatial and spatiotemporal data can be modeled by these approaches.
Spatial Auto-regressive Dependency Interpretable Learning Based on Spatial Topological Constraints
A novel convex framework that automatically jointly learns the prediction mapping and spatial dependency based on spatial topological constraints with a theoretical guarantee is proposed and transferred to convex problems that can be iteratively optimized by the proposed algorithms.


Two-Step Lasso Estimation of the Spatial Weights Matrix
The vast majority of spatial econometric research relies on the assumption that the spatial network structure is known a priori. This study considers a two-step estimation strategy for estimating the
Regularization for Spatial Panel Time Series Using the Adaptive LASSO
Non-asymptotic oracle oracle inequalities and the asymptotic sign consistency of the estimators are proved when the dimension of the time series can be larger than the sample size, and they tend to infinity jointly.

Detection and Estimation of Block Structure in Spatial Weight Matrix
In many economic applications, it is often of interest to categorize, classify, or label individuals by groups based on similarity of observed behavior. We propose a method that captures group
An Anisotropic Model for Spatial Processes
One of the key assumptions in spatial econometric modelling is that the spatial process is isotropic, which means that direction is irrelevant in the specification of the spatial structure. On one

ABSTRACT In this article, we consider a high-dimensional quantile regression model where the sparsity structure may differ between two sub-populations. We develop ℓ1-penalized estimators of both
A Generalized Moments Estimator for the Autoregressive Parameter in a Spatial Model
This paper is concerned with the estimation of the autoregressive parameter in a widely considered spatial autocorrelation model. The typical estimator for this parameter considered in the literature
Specification of spatial models: A simulation study on weights matrices
The sensitivity of testing and estimating spatial models with different weights matrix specifications is studied and recommendations for researchers applying spatial models regarding model selection and weights matrix specification are formulates.
