Robust product Markovian quantization

In this paper the authors formulate the one-dimensional RMQ and d-dimensional PMQ algorithms as standard vector quantization problems by deriving the density, distribution and lower partial expectation functions of the random variables to be quantized at…

Severe but plausible – or not?

In this paper, the authors apply a measure of statistical unusualness, called the Mahalanobis distance, to assess the plausibility of the scenarios used in the Federal Reserve's stress tests.

Regularization effect on model calibration

This paper compares two methods to calibrate two popular models that are widely used for stochastic volatility modeling (ie, the SABR and Heston models) with the time series of options written on the Nasdaq 100 index to examine the regularization effect…

Climate risk and central counterparty risk management

In this paper, the European Association of CCP Clearing Houses discusses several aspects of climate risk, including how climate risk is currently integrated into central counterparty stress testing, the metrics within climate risk and how central…
