The costs of not knowing the radius
Rieder, Helmut; Kohl, Matthias; Ruckdeschel, Peter - 2001
We determine the increase of the maximum risk over the minimax risk in the case that the optimally robust estimator for … the relative risk is minimized in the case that the radius is known only to belong to some interval [pr, l'/p] " The … effect of increasing parameter dimension is studied for these models. The minimax increase of relative risk in ease p = 0 …

Investigation of the stochastic utility maximization process of consumer brand choice by semiparametric modeling
Abe, Makoto; Boztuğ, Yasemin; Hildebrandt, Lutz - 2000
The use of nonparametric methods, which posit fewer assumptions and greater model flexibility than parametric methods, could provide useful insights when studying brand choice. It was found, however, that the data requirement for a fully nonparametric brand choice model is so great that...

The influence of inventory effects and reference points on the rate of consumption
Bell, David R.; Boztuğ, Yasemin - 2001 - Rev.
The authors develop and test a model to study the influence of inventory-on-hand and price-based reference points on the consumption rate of consumers. The model is motivated by recent theoretical and empirical research which suggests inventory pressure can cause consumers to increase...
