case 1 : Auxiliary variables only contains variable with error in aux variable | Load Package and Load Data Set | Fitting HB Model | Ekstract Mean Estimation | Small Area Mean Estimation | Coefficient Estimation | Random Effect Variance Estimation | Extract MSE | Extract RSE | You can compare with Direct Estimation | Extract Direct Estimation | Comparing Y | Comparing Mean Squared Error (MSE) | Comparing Relative Standard Error (RSE) | case 2: Auxiliary variables contains variable with error and without error | note : you can use dataHBMEbetaNS for using dataset with non-sampled area
