To accomplish this, a Monte Carlo simulation approach is employed to estimate de default ratio based on predetermined ”real” probabilities of default. By simulating different scenarios, we can assess the potential bias and evaluate the need for adjustments, such as confidence level modifications or the inclusion of a Margin of Conservatism (MoC), to account for estimation uncertainty.32 p.application/pdfengcc-by-nc-nd (c) Ventura Horán, 2024http://creativecommons.org/licenses/by-nc-nd/3.0/es/Risc de crèditMètode de MontecarloAvaluació del riscTreballs de fi de màsterCredit riskMonte Carlo methodRisk assessmentMaster's thesisCredit risk measures and the estimation error in the ASRF model under the Basel II IRB approachinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
