On Ignorability of Preferential Sampling in Geostatistics
Changqing Lu, Ganggang Xu, Junho Yang +1
Preferential sampling has attracted considerable attention in geostatistics since the pioneering work of Diggle et al. (2010). A variety of likelihood-based approaches have been de…
Generalized Reduced-Rank Regression with Homogeneity Pursuit
Ruipeng Dong, Ganggang Xu, Yongtao Guan
Homogeneity, low rank, and sparsity are three widely adopted assumptions in multi-response regression models to address the curse of dimensionality and improve estimation accuracy.…
XGBoostPP: Tree-based Estimation of Point Process Intensity Functions
C. Lu, Y. Guan, M. N. M. van Lieshout +1
We propose a novel tree-based ensemble method, named XGBoostPP, to nonparametrically estimate the intensity of a point process as a function of covariates. It extends the use of gr…
Fourier analysis of spatial point processes
Junho Yang, Yongtao Guan
In this article, we develop comprehensive frequency domain methods for estimating and inferring the second-order structure of spatial point processes. The main element here is on u…
