Sample Data for Small Area Estimation using Hierarchical Bayesian Method under Zero-Inflated Binomial Distribution

Description

Dataset to simulate Small Area Estimation using Hierarchical Bayesian Method under Zero-Inflated Binomial distribution

This data is generated by these following steps:

1. Generate sampling random area effect u.Z and u.nZ with (u.Z ~ N(0,1)) and (u.nZ ~ N(0,1)). The auxilary variabels are generated by Uniform distribution with (x1 ~ U(0,1)) and (x2 ~ U(1,5)). The coefficient parameters \alpha0, \alpha1, \alpha2, \beta0, \beta1, \beta2 are set as 0.

2. Calculate logit(p)=\alpha0 + \alpha1 * x1+ \alpha2 * x2 + u.Z and logit(\pi)=\beta0 + \beta1 * x1 +\beta2 * x2 + u.nZ

3. Generate number of sample with n.samp ~ U(10,30)

4. Generate delta ~ bernoulli(p) and y_star ~ binomial(s, \pi)

5. calculate y = delta*y_star

6. Calculate variance of direct estimates (vardir) with var (y) = (1-p)*s*pi*(1-\pi*(1-p*s))

7. Auxilary variables x1, x2, direct estimation (y), vardir, and s are combined in a dataframe called dataZIB
