Data organized in spatial lattices (e.g., semiconductor die grids, agricultural field trials) are commonly modeled using spatial autoregressive processes. When outliers are present in the data, classical parameter estimation techniques for these models, such as least squares and maximum likelihood, can be inefficient and potentially mislead the analyst… CONTINUE READING
