Adjacency Matrix for Conditional Autoregressive (CAR)

Description

The adjacency_matrix_car contains a symmetric adjacency matrix used for demonstrating Hierarchical Bayesian Small Area Estimation (HB SAE) with spatial structure under the Conditional Autoregressive (CAR) model. The matrix consists of 0s and 1s to represent neighborhood relationships between areas, where a value of 1 indicates direct adjacency. This structure is commonly used in CAR models to specify spatial dependence based on local neighborhood connections.

Usage

adjacency_matrix_car

Format

A 5×5 numeric matrix with row and column names "1" to "5".

Source

Simulated example created for illustrating spatial structure in CAR models.
