Researchers have compared various scalable Gaussian process approximations for handling large spatial datasets. Their analysis focused on the trade-off between model accuracy and computational runtime across simulated and real-world data. The study found that Vecchia approximations consistently offered the best balance of accuracy and speed for likelihood evaluation, parameter estimation, and prediction. AI
