7.3. Experiment
- 1.
- Assume some true values of the parameters and compute the corresponding true values ofCase 1: If , thenCase 2: If , thenCase 3: If , thenCase 4: If , then
- 2.
- Use the algorithm in Section 7.2 to generate different sample sizes with and 100, with 10,000 replications. All computations are obtained using Mathematica 11.1.
- 3.
- Calculate according to the methodology in Section 6.1 and the “average ”, say , based on all the samples at a fixed size.
- 4.
- Evaluate the ACI and BCI according to the methodology in Section 6.2 and Section 7.2.
- 5.
- Study the behavior of by evaluating the bias defined by the “average of ” and the mean square error (MSE) indicated as the “average of ”.
- 6.
- In the context of interval estimation, we compare the ACI and BCI using the asymptotic confidence length (ACL) and converge probability (CP).
- 1.
- At , the value of the MSE becomes very small.
- 2.
- In general, the length of the ACI becomes smaller than the length of the BCI.
- 3.
- When the ACL decreases, the CP increases.
- 4.
- The CP in almost all cases of the ACI is more than the CP in the BCI.
8. Application: Household Financial Affordability in KSA 2018
- Case 1: If X and Y are independent with X following the GHLD and Y following the GHLD, and the dependent parameter is set as 0;
- Case 2: If X and Y are dependent with , following the FGMBGHLD.
- 1.
- Since is estimated as , and is therefore positive, then the relation between X and Y is positive, as we see in Figure 3.
- 2.
- The measure of affordability when X and Y are dependent is less than when X and Y are independent, so the case of dependent variables is more realistic.
- Case 1: If X and Y are independent with X following the and Y following the ;
- Case 2: If X and Y are dependent with , following the BWD.
