The near-extreme density of intraday log-returns
near-extreme density intraday log-returns tatistics
2011/7/4
The extreme event statistics plays a very important role in the theory and
practice of time series analysis. The reassembly of classical theoretical results
is often undermined by non-stationarity a...
Density Approximations for Multivariate Affine Jump-Diffusion Processes
Affine Processes Asymptotic Expansion Density Approximation
2011/7/25
Abstract: We introduce closed-form transition density expansions for multivariate affine jump-diffusion processes. The expansions rely on a general approximation theory which we develop in weighted Hi...
Bayesian estimation of GARCH model with an adaptive proposal density
Bayesian estimation GARCH model adaptive proposal density
2011/1/4
A Bayesian estimation of a GARCH model is performed for US Dollar/Japanese Yen exchange rate by the Metropolis-Hastings algorithm with a proposal density given by the adaptive construction scheme. In ...
Conditional Density Models for Asset Pricing
option pricing implied volatility Breeden-Litzenberger equation
2010/10/22
We model the dynamics of asset prices and associated derivatives by consideration of the dynamics of the conditional probability density process for the value of an asset at some specified time in the...
Density quantization method in the optimal portfolio choice with partial observation of stochastic volatility
Optimal portfolio partial observation ltering density
2010/10/21
Computational aspects of the optimal consumption and investment with the partially observed stochastic volatility of the asset prices are considered. The new quantization approach to filtering - dens...
Nonparametric methods for volatility density estimation
stochastic volatility models deconvolution density estimation kernel estimator wavelets minimum contrast estimation
2010/11/2
Stochastic volatility modelling of nancial processes has become increasingly popular. The proposed models usually contain a stationary volatility process. We will motivate and review several nonparam...
State price density estimation via nonparametric mixtures
Black–Scholes equation European call options nonparametric mixture state price density
2010/11/2
We consider nonparametric estimation of the state price density encapsulated in option prices. Unlike usual density estimation problems,we only observe option prices and their corresponding strike pri...
Asymptotic Behavior of the Stock Price Distribution Density and Implied Volatility in Stochastic Volatility Models
true martingales one-dimensional diffusions separating times financial bubbles
2010/11/1
The stochastic exponential Zt = exp{Mt − M0 − (1/2)hM,Mit} of a continuous local martingale M is itself a continuous local martingale. We give a necessary and sufficient condition for the ...
Probabilistic representations of the density function of the asset price and of vanilla options in linear stochastic volatility models

2010/11/2
Probabilistic representations of the density function of the asset price and of vanilla options in linear stochastic volatility models。
Bayesian inference with an adaptive proposal density for GARCH models
Bayesian inference adaptive proposal GARCH models
2010/11/2
We perform the Bayesian inference of a GARCH model by the Metropolis-Hastings algorithm with an adaptive proposal density. The adaptive proposal density is assumed to be the Student’s t-distribution a...
Effects of Plant Population Density on Net Revenues from Ultra-Narrow-Row Cotton
Plant Population Density Net Revenues Ultra-Narrow-Row Cotton
2008/12/10
A common characteristic of ultra-narrow-row cotton (Gossypium hirsutum L.) production is the use of high plant population densities (PPD) compared to wide-row cotton. Farmers are concerned about the h...

2011/4/2
Most existing empirical studies on affine term structure models (ATSMs) have mainly focused on in-sample goodness-of-fit of historical bond yields and ignored out-of-sample forecast of future bond yie...
