Quantifying uncertainty of machine learning methods for loss given default

نویسندگان

چکیده

Machine learning has increasingly found its way into the credit risk literature. When applied to forecasting parameters, approaches have been outperform standard statistical models. The quantification of prediction uncertainty is typically not analyzed in machine setting. However, this vital interests managers and regulators alike as increases transparency stability management reporting tasks. We fill gap by applying novel approach deep evidential regression loss given defaults (LGDs). evaluate aleatoric epistemic for LGD estimation techniques apply explainable artificial intelligence (XAI) methods analyze main drivers. find that considerably larger than uncertainty. Hence, majority estimates appears be irreducible it stems from data itself.

Estimating Conservative Loss given Default

The new Basel Capital Accord (Basel II) is going to be embedded in the risk management practices at many financial institutions shortly, but the academic and financial world are still discussing about several topics related to the new capital adequacy rules. One of the most important and prominent examples among these topics is the link between loss given default (LGD) and the economic cycle. I...

Loss given default as a function of the default rate

A recently derived function ties a portfolio’s loss given default rate (LGD) to its default rate. This study compares the predictive performance of the LGD function to that of linear regression using simulated data. The data are simulated using a linear model. Even though this confers an advantage to linear regression, the LGD function produces lower mean squared error over a meaningful range o...

Calculation of Portfolio Loss Distribution Given Default

Default loss distribution of corporate portfolios plays a crucial role in CDO tranche pricing, tracking error calculation and profit/loss assessment of corporation systems. This work gives an efficient algorithm to calculate the default loss distribution based on Hull-White probability bucketing approach and importance sampling method. The Gaussian copula model is assumed to calculate the condi...

Two models of stochastic loss given default

We propose two structural models for stochastic loss given default that allow the credit losses of a portfolio of defaultable financial instruments to be modeled. The credit losses are integrated into a structural model of default events accounting for correlations between the default events and the associated losses. We show how the models can be calibrated and analyze the impact of correlatio...

Forecasting bank loans loss-given-default

With the advent of the new Basel Capital Accord, banking organizations are invited to estimate credit risk capital requirements using an internal ratings based approach. In order to be compliant with this approach, institutions must estimate the expected loss-given-default, the fraction of the credit exposure that is lost if the borrower defaults. This study evaluates the ability of a parametri...
