Nonparametric Stochastic Volatility [PDF]
SSRN Electronic Journal, 2010 We provide nonparametric methods for stochastic volatility modeling. Our methods allow for the joint evaluation of return and volatility dynamics with nonlinear drift and diffusion functions, nonlinear leverage effects, and jumps in returns and volatility with possibly state-dependent jump intensities, among other features.

Construction of an Entropy Estimator with a Special Metrics and an Arbitrary Function
Моделирование и анализ информационных систем, 2013 The paper proposes a generalization of entropy as in [1]. At first, to constract the estimator, we select the metrics on the space of sequances. This metrics is based on a matrix that can be interpreted as an edge coloring of a complete graph with loops.

A comparison of phase I control charts
South African Journal of Industrial Engineering, 2015 A carefully done Phase I analysis is a vital part of an overall statistical process control and monitoring regime. Distribution-free control charts can play a useful role in this analysis, as a parametric model assumption often cannot be adequately ...

NONPARAMETRIC SIGNIFICANCE TESTING [PDF]
Econometric Theory, 2000 A procedure for testing the significance of a subset of explanatory variables in a nonparametric regression is proposed. Our test statistic uses the kernel method. Under the null hypothesis of no effect of the variables under test, we show that our test statistic has an nhp2/2 standard normal limiting distribution, where p2 is the dimension of ...
