Sample Data for Small Area Estimation using Hierarchical Bayesian Method under Multivariate T distribution

Description

Dataset to simulate Small Area Estimation using Hierarchical Bayesian Method under Multivariate T distribution

This data is generated by these following steps:

1. Generate sampling error e, random effect u, and auxiliary variables X1 X2.

   • For sampling error e, we set e_{d} is multivariate T distributed where the vector of noncentrality parameters is zero, scale matrix V_{ed} = (\sigma_{dij})_{i,j=1,2,3}, with \sigma_{ii} ~ InvGamma(a, b) and \rho_{e} = 0.5, and degree of freedom df ~ InvGamma(a, b).

   • For random effect u, we set u ~ N_{3}(0, V_{u}).

   • For auxiliary variables X1 and X2, we set X1 ~ UNIF(1,2) and X2 ~ UNIF(1, 10).

2. Calculate direct estimation Y1 Y2 and Y3 , where Y_{i} = X * \beta + u_{i} + e_{i}. We take \beta_{1} = 1 and \beta_{2} = 1.

Auxiliary variables X1 X2, direct estimation Y1 Y2 Y3, and sampling variance-covariance v1 v2 v3 v12 v13 v23 are combined into a dataframe called datasaeT
