Realization is not just a statistical validation like a Kolmogorov-Smirnov test.
The simplest way to explain it is that the execution of a KS test only compares distributions; it is an analytical step.
A true realization involves an action that has a real impact, not just a measure.
For example, the MAS realizes a exchange rate policy through direct interventions in the foreign exchange market, not by analyzing data afterward.
KS tests are just a diagnostic tool, not the mechanism of the policy itself.
