The spatial_weight_sar dataset contains a standardized spatial weight matrix designed
for use in Hierarchical Bayesian Small Area Estimation (HB SAE) under the
Simultaneous Autoregressive (SAR) model.
The matrix represents spatial influence between areas with continuous, non-negative weights,
and is symmetric with zeros on the diagonal.
This structure allows modeling of spatial autocorrelation with varying intensity across regions.
