Let (X1, Y1), . . ., (Xn, Yn) be i.i.d. rvs and let l(x) be the unknown p-quantile regression curve of Y on X. A quantile-smoother ln(x) is a localised, nonlinear estimator of l(x). The strong uniform consistency rate is established under general conditions. In many applications it is necessary...

with nonparametric estimation of the pricing kernel (Empirical Pricing Kernel) given by the ratio of the risk …Pricing kernels implicit in option prices play a key role in assessing the risk aversion over equity returns. We deal … testing parametric specifications of pricing kernels and has a direct extension to estimating risk aversion patterns. The …

Generalized additive models (GAM) are multivariate nonparametric regressions for non-Gaussian responses including binary and count data. We propose a spline-backfitted kernel (SBK) estimator for the component functions. Our results are for weakly dependent data and we prove oracle efficiency....

It is an undisputed fact that weather risk increases over time due to climate change. However, qualification of this … statement with regard to the type of weather risk and geographical location is needed. We investigate the application of novel … statistical tools for assessing changes in weather risk over time. We apply local t-test, change point tests and Mann-Kendall test …

In this paper bootstrap confidence bands are constructed for nonparametric quantile estimates of regression functions, where resampling is done from a suitably estimated empirical distribution function (edf) for residuals. It is known that the approximation error for the confidence band by the...

In this paper uniform confidence bands are constructed for nonparametric quantile estimates of regression functions. The method is based on the bootstrap, where resampling is done from a suitably estimated empirical density function (edf) for residuals. It is known that the approximation error...
