1) Geo-additive models of Childhood Undernutrition in three Sub-Saharan African Countries
We investigate the geographical and socioeconomic determinants of childhood undernutrition in Malawi, Tanzania and Zambia, three neighboring countries in Southern Africa using the 1992 Demographic and...Show More
2) Missing at Random (MAR) in Nonparametric Regression - A Simulation Experiment
This paper considers an additive model y = f(x) + e when some observations on x are missing at random but corresponding observations on y are available. Especially for this model missing at random is ...Show More
3) Quantifying overdispersion effects in count regression data
The Poisson regression model is often used as a first model for count data with covariates. Since this model is a GLM with canonical link, regression parameters can be easily fitted using standard sof...Show More
4) Graphical chain models for the analysis of complex genetic diseases: an application to hypertension
A crucial task in modern genetic medicine is the understanding of complex genetic diseases. The main complicating features are that a combination of genetic and environmental risk factors is involved,...Show More
5) Parametric and Nonparametric Regression with Missing X's - A Review
This paper gives a detailed overview of the problem of missing data in parametric and nonparametric regression. Theoretical basics, properties as well as simulation results may help the reader to get ...Show More
6) A Selection Model for Bivariate Normal Data, with a Flexible Nonparametric Missing Model and a Focus on Variance Estimates
Nonignorable nonresponse is a common problem in bivariate or multivariate data. Here a selection model for bivariate normal distributed data (Y1 ; Y2) is proposed. The missingness of Y2 is supposed to...Show More
7) The association between reported and calculated reservation wages
Do reported reservation wages correspond to the concept of reservation wages that economists have? Using panel data on British unemployed I calculate reservation wages from a search model and compare ...Show More
8) The Tail of the Stationary Distribution of a Random Coefficient AR(q) Model
We investigate a stationary random cofficient autoregressive process. Using renewal type arguments tailor-made for such processes we show that the stationary distribution has a power-law tail. When th...Show More
9) A Smooth Test in Proportional Hazard Survival Models using Local Partial Likelihood Fitting
Proportional hazard models for survival data, even though popular and numerically handy, suffer from the restrictive assumption that covariate effects are constant over survival time. A number of test...Show More
10) A comparison of asymptotic covariance matrices of three consistent estimators in the Poisson regression model with measurement errors
We consider a Poisson model, where the mean depends on certain covariates in a log-linear way with unknown regression parameters. Some or all of the covariates are measured with errors. The covariates...Show More
