In this paper the authors study different moving-window lengths for value-at-risk evaluation, and also address subjectivity in choosing the window size by

This paper introduces a prudent methodology to accurately estimates loss given default for mortgage portfolios and to stress test those portfolios effectively.

Riskalyze Campaign Attacks Orions HiddenLevers, RiXtrema Citing fiduciary responsibilities, Riskalyze CEO Aaron Klein is publicly targeting the wildly inaccurate and predictive guesswork of his competitors. A long-simmering confrontation in the advisor technology space is spilling into public view. Riskalyze co-founder and CEO Aaron Klein is launching a highly visible campaign to discredit the risk methodologies used by competitors. Squarely in the crosshairs are risk analytics platfo...

Journal of Risk Model Validation 24 February 2021 Beyond the contract: client behavior from origination to default as the new set of the loss given default risk drivers Parametric and non-parametric models are prepared for the recovery rate estimation. Adding client related variables reduces the errors and improve discrimination. The effect is more visible for fractional regression rather than regression tree. Abstract Modeling loss given default has increased in popularity as i...

Need to know The model proposed in this paper enables the drawing of ROC curves for credit scoring without underlying data. The "bifractal" ROC function fits well with the empirical curves. The results show that the Gini coefficient of a scorecard will almost always drop if computed only above the cutoff. Abstract This paper formulates a mathematical model for generating receiver operating characteristic (ROC) curves without underlying data. Credit scoring practitioners know that the Gini coeff...

This paper analyzes the relationship between option risk and expected return from the perspective of the underlying beta, and estimates the degree of

This study evaluates the efficiency of the hybrid classifier. The study found that the clustering based LR + MLP hybrid classifier efficient across all of the criteria. Among the other classifiers, MLP based hybrid classifiers also achieved superior performance. Abstract This paper examines which hybridization strategy is more suitable for credit risk assessment in the dynamic financial world. As such, we use extensive new data sets and develop different hybrid models by combining traditional s...
