We prove geometric ergodicity and absolute regularity of the nonparametric autoregressive bootstrap process. To this … sequence. This is achieved by using well-established coupling techniques. Then we apply the result to the bootstrap process and … bootstrap process has the desired properties. Moreover, by using some 'decoupling' argument, we show that the stationary density …

generalized linear model kernel regression constructed estimators with lower order bias than the usual estimators, without the … estimator in the context of local (multivariate) estimation based on estimating functions. As expected, this lower order bias is …, the bias-corrected estimators increase variance by a factor independent of the problem, depending only on the kernel used …

we show that the bootstrap is able to capture the negative bias and the skewness of the test statistic. It yields better … fixed link functions. In this paper we consider a bootstrap specification test that detects nonparametric deviations of the … link function. The bootstrap is used with the aim to find a more accurate distribution under the null than the normal …

In this paper we introduce a bootstrap procedure to test parameter restrictions in vector autoregressive models which … is robust in cases of conditionally heteroskedastic error terms. The adopted wild bootstrap method does not require any … Monte Carlo investigation empirical size and power properties of the new method are illustrated. We compare the bootstrap …

One puzzling behavior of asset returns for various frequencies is the often observed positive autocorrelation at lag 1. To some extent this can be explained by standard asset pricing models when assuming time varying risk premia. However, one often finds better results when directly fitting an...
