Aboveground Storage Tank(AST) testing using statistical approach
Based on the original Statistical Inventory Reconciliation(SIR) Test Method (Quantitative), K-folds cross validation is used to increase P(D) and decrease P(FA) by adjusting K, which are related to bias and standard deviation. There is a trade-off between bias and variance, with very flexible models (overfit) having low bias and high variance, and relatively rigid models(underfit) having high bias and low variance. When K is larger, we have lower bias and larger standard deviation. Also, K-folds cross validation is very useful, when data size is small. So this methods has a higher validity with a lower data requirement.
