Academic ranking scales in economics : prediction and imputation
Zharova, Alona; Mihoci, Andrija; Härdle, Wolfgang - 2016
Publications are a vital element of any scientist’s career. It is not only the number of media outlets but aslo the quality of published research that enters decisions on jobs, salary, tenure, etc. Academic ranking scales in economics and other disciplines are, therefore, widely used in...

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...

Confidence corridors for multivariate generalized quantile regression
Chao, Shih-kang; Proksch, Katharina; Dette, Holger; … - 2014
We focus on the construction of confidence corridors for multivariate nonparametric generalized quantile regression functions. This construction is based on asymptotic results for the maximal deviation between a suitable nonparametric estimator and the true function of interest which follow...

Do maternal health problems influence child's worrying status? : evidence from British cohort study
Dai, Xianhua; Härdle, Wolfgang; Yu, Keming - 2014
The influence of maternal health problems on child's worrying status is important in practice in terms of the intervention of maternal health problems early for the influence on child's worrying status. Conventional methods apply symmetric prior distributions such as a normal distribution or a...
