Estimating the Value-at-Risk from High-frequency Data
Data augmentation Gibbs sampler Quadratic variation Time changed Brownian motion
2016/1/27
We present two alternative approaches for estimating VaR. Both approaches are based on the observation that each trading day is very diverse and we can observe K different phases of the trading day. W...
Defining, Estimating and Using Credit Term Structures. Part 3: Consistent CDS-Bond Basis
Estimating Credit Term Structures Consistent CDS-Bond Basis
2010/11/3
In the third part of this series we introduce consistent relative value measures for CDS-Bond
basis trades using the bond-implied CDS term structure derived from fitted survival rate
curves. We expl...

Estimating Term Structures Consistent Risk Measures
2010/11/3
In the second part of our series we suggest new definitions of credit bond duration and
convexity that remain consistent across all levels of credit quality including deeply distressed bonds and intr...
Defining, Estimating and Using Credit Term Structures. Part 1: Consistent Valuation Measures
Defining, Estimating Consistent Valuation Measures
2010/11/3
In this three-part series of papers, we argue that the conventional spread measures are not
well defined for credit-risky bonds and introduce a set of credit term structures which correct
for the bi...
Estimating financial risk measures for futures positions: a non-parametric approach
spectral risk alternative measures financial risk
2011/3/31
This paper presents non-parametric estimates of spectral risk measures applied to long and short positions in 5 prominent equity futures contracts. It also compares these to estimates of two popular a...
Nonparametric Methods for Estimating Conditional VaR and Expected Shortfall
Bandwidth selection Boundary effects Coherent risk measurements Empirical likelihood Expected shortfall Local liner estimation Nonparametric smoothing Quantile regression Time series Value-at-risk Weighted double kernel
2011/4/6
In this article we propose a new nonparametric estimation method to estimate the
conditional value-at-risk and expected shortfall functions based on the weighted double
kernel local linear estimator...
