We propose a new class of spatio-temporal models with unknown and banded autoregressive coefficient matrices. The setting represents a sparse structure for high-dimensional spatial panel dynamic models when panel members represent economic (or other type) individuals at many different locations. The structure is practically meaningful when the order of panel members is arranged appropriately. Note that the implied autocovariance matrices are unlikely to be banded, and therefore, the proposal is…

Sparse spatio-temporal autoregressions by profiling and bagging

Sparse Generalized Yule-Walker Estimation for Large Spatio-temporal Autoregressions with an Application to NO2 Satellite Data

We consider sparse estimation of a class of high-dimensional spatio-temporal models. Unlike classical spatial autoregressive models, we do not rely on a predetermined spatial interaction matrix.…

A flexible spatial autoregressive modelling framework for mixed covariates of multiple data types

An estimation method is developed based on functional principal component analysis (FPCA), the isometric logratio (ilr) transformation and the maximum likelihood estimation (MLE) method for an SAR model that has the merits of classical functional linear models and compositional linear models with scalar responses.

Factor analysis for high‐dimensional time series: Consistent estimation and efficient computation

A new approach based on the eigenvalues of a non‐negative definite matrix for consistently determining the number of factors is proposed, which is computationally efficient with a single step procedure, especially when both weak and strong factors exist in the factor model.

Simultaneous Decorrelation of Matrix Time Series*

The uniform convergence rates of the estimated transformation are derived, which vindicate an important virtue of the proposed bilinear transformation, i.e. it is technically equivalent to the decorrelation of a vector time series of dimension max( p, q ) instead of p × q .

Structural-Factor Modeling of High-Dimensional Time Series: Another Look at Approximate Factor Models with Diverging Eigenvalues

A new approach to modeling high-dimensional time series data by providing a simple and natural way to understand the mechanism of factor models is proposed, which not only provides interpretable results, but also performs well in out-of-sample forecasting.

Structural-Factor Modeling of High-Dimensional Time Series: Another Look at Factor Models with Diverging Eigenvalues

Finite sample theory for high-dimensional functional/scalar time series with applications

A new perspective on dependence is introduced by proposing functional cross-spectral stability measure to characterize the effect of dependence on these estimated cross terms, which are essential in the estimates for additive functional linear regressions.
