Estimation and testing for varying coefficients in additive models with marginal integration
Yang, Lijian; Härdle, Wolfgang; Park, Byeong U. - 2002
We propose marginal integration estimation and testing methods for the coefficients of varying coefficient multivariate … regression model. Asymptotic distribution theory is developed for the estimation method which enjoys the same rate of convergence … as univariate function estimation. For the test statistic, asymptotic normal theory is established. These theoretical …

Increasing weather risk : fact of fiction?
Wang, Weining; Bobojonov, Ihtiyor B.; Härdle, Wolfgang; … - 2011
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...

Common factors in credit defaults swaps markets
Chen, Yi-Hsuan; Härdle, Wolfgang - 2012
We examine what are common factors that determine systematic credit risk and estimate and interpret the common risk factors. We also compare the contributions of common factors in explaining the changes of credit default swap (CDS) spreads during the pre-crisis, crisis and post-crisis period....
