Difference between simulated samples and true data () as related to significance level of difference between the accessible and inaccessible samples through the
-test.
The bar height represents the measure of dQ, and the color represents the significance levels of the -test. The last plot shows the significance levels. indicates a significant difference between the accessible and inaccessible samples through the tests of association ( p-value < 0.5, **p-value < 0.1, ***p-value < 0.01).

Difference between simulated samples and true data () as related to significance level of SPRTBA/logistic regression for finding an association between seed variables and selected variables.
The bar height represents the measure of dQ, and the color represents the significance levels of the SPRTBA/logistic regression. The last plot shows the significance levels. † indicates a significant association using SPRTBA/logistic regression between Seed variables and selected variables (†p-value < 0.5, ††p-value < 0.1, †††p-value < 0.01).
