Self-rated and changes in self-rated health as predictors of mortality : first evidence from german panel data

Schwarze, Johannes; Andersen, Hanfried H.; Anger, Silke - 2002

Background: Studies from several countries have shown that self-rated health is an independent predictor of mortality … individuals and (ii) changes in self-rated health, as predictors of mortality for Germany. Methods: A sub-sample of 3 … in self-rated health on predictions of mortality. Results: We find that, while currently self-rated health is shown to be …

Bootstrap inference in single equation error correction models

Herwartz, Helmut; Neumann, Michael H. - 2000

In the sequel of its seminal application in Davidson, Hendry, Srba and Yeo (1978) the single equation error correction model has been widely used in empirical practice. Providing a clear distinction between short- and long-run dynamics this model allows OLS-methods to be as efficient as...

A nonparametric regression estimator that adapts to error distribution of unknown form

Linton, Oliver; Xiao, Zhijie - 2001

We propose a new estimator for nonparametric regression based on local likelihood estimation using an estimated error score function obtained from the residuals of a preliminary nonparametric regression. We show that our estimator is asymptotically equivalent to the infeasible local maximum...

Robust estimation in nonlinear regression and limited dependent variable models

Čížek, Pavel - 2001

Classical parametric estimation methods applied to nonlinear regression and limited-dependent-variable models are very sensitive to misspecification and data errors. On the other hand, semiparametric and nonparametric methods, which are not restricted by parametric assumptions, require more data...

The dynamics of implied volatilities : a common principal components approach

Fengler, Matthias R.; Härdle, Wolfgang; Villa, Christophe - 2001

It is common practice to identify the number and sources of shocks that move implied volatilities across space and time by applying Principal Components Analysis (PCA) to pooled covariance matrices of changes in implied volatilities. This approach, however, is likely to result in a loss of...

Smoothed influence function : another view at robust nonparametric regression

Tamine, Julien - 2001

In this work, we introduce a smoothed influence function that constitute a theoretical tool for studying the outliers robustness properties of a large class of nonparametric estimators. With this tool, we first show the nonrobustness of the Nadaraya-Watson estimator of regression. Then we show...
