Autoren-Abstract: This paper introduces ideas and methods for testing for structural change in linear regression models and presents how these have been realized in an R package called strucchange. It features tests from the generalized fluctuation test framework as well as from the F test (Chow...

We show how the rootogram - a graphical tool associated with the work of J. W. Tukey and originally used for assessing goodness of fit of univariate distributions - can help to diagnose and treat issues such as overdispersion and/or excess zeros in regression models for count data. Two empirical...

We decompose the generalized Lorenz order into a size and a distribution component. The former is represented by stochastic dominance, the latter by the standard Lorenz order. We show that it is always possible, given generalized Lorenz dominance between two distributions F and G, to find...

The classical approach to testing for structural change employs retrospective tests using a historical data set of a given length. Here we consider a wide array of fluctuation-type tests in a monitoring situation – given a history period for which a regression relationship is known to be...

OLS is as efficient as GLS in the linear regression model with long-memory errors as the long-memory parameter approaches the boundary of the stationarity region_ provided the model contains a constant term. This generalizes previous results of Samarov Taqqu (Journal of Time Series Analysis 9...

This paper obtains Lorenz ordering relationships among order statistics from log-logistic samples of possibly different sizes. Some results extend other families including the Lomax, Burr III and Burr XII distributions.

Reproducibility of economic research has attracted considerable attention in recentyears. So far, the discussion has focused on reproducibility of empirical analyses. Thispaper addresses a further aspect of reproducibility, the reproducibility of computationalexperiments. We examine the current...

In a series of papers in the 1970s, Camilo Dagum proposed several variants ofa new model for the size distribution of personal income. This Chapter traces thegenesis of the Dagum distributions in applied economics and points out paralleldevelopments in several branches of the applied statistics...

This paper surveys selected applications of the Lorenz curve and related stochasticorders in economics and econometrics, with a bias towards problems in statisticaldistribution theory. These include characterizations of income distributions in termsof families of inequality measures, Lorenz...
