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.
