Bijmolt, T.H.A., Wedel, M., DeSarbo, W.S.
We propose Adaptive Multidimensional Scaling (AMDS) for simultaneously deriving a brand map and market segments using consumer data on cognitive decision sets and brand dissimilarities. In AMDS, the...
Rising levels of advertising competition have made it increasingly difficult to atract and hold consumer's attention and to establish strong memory traces for the advertised brand. A common...
Time Aggregation Effects on the Baseline of Continuous-Time and Discrete-Time Hazard Models (1999)
In this study we reinvestigate the effect of time-aggregation for discrete- and continuous-time hazard models. We reanalyze the results of a previous Monte Carlo study by ter Hofstede and Wedel...
Export market information behaviour of SME's : the influence of firm characteristics (1998)
Voerman, J.A., Wedel, M., Zwart, P.S.
The magic word of the last years is internationalization. Researchers more and more focus on export market information and the relationship between this information and export performance. Just a few...
This study investigates the effects of time aggregation in discrete and continuous-time hazard models. A Monte Carlo study is conducted in which data are generated according to various continuous and...
Mixed tree and spatial representation of dissimilarity judgment (1998)
Whereas previous research has shown that either tree or spatial representations of dissimilarity judgments may be appropriate, focussing on the comparative fit at the aggregate level, we investigate...
Mixture model analysis of complex samples (1997)
This paper investigates asymmetric effects of monetary policy over the business cycle. A two-state Markov Switching Model is employed to model both recessions and expansions. For the United States...
A Monte Carlo evaluation of maximum likelihood multidimensional scaling methods (1996)
We compare three alternative Maximum Likelihood Multidimensional Scaling methods for pairwise dissimilarity ratings, namely MULTISCALE, MAXSCAL, and PROSCAL in a Monte Carlo study. The three MLMDS...

WEDEL, M., PIETERS, J. E., PIKAAR, N. A., OCKHUIZEN, Th.
A recently developed three-compartment model for the absorption and elimination of ingested alcohol was applied to re-analyse a study on the effects of various factors known to influence the...

PARAMETER ESTIMATION IN A THREE-COMPARTMENT MODEL FOR BLOOD ALCOHOL CURVES (1990)
PIETERS, J. E., WEDEL, M., SCHAAFSMA, G.
Models of alcohol input and absorption are crucial to the description and understanding of the effects of alcohol in the human body. In this paper, the pharmacokinetics of alcohol after oral...
INFLUENCE OF SEVERAL FACTORS ON BLOOD ALCOHOL CONCENTRATIONS AFTER DRINKING ALCOHOL (1988)
PIKAAR, N. A., WEDEL, M., HERMUS, R. J. J.
The influence of several factors on the blood alcohol course after drinking diluted ethanol was studied in young, healthy volunteers under strictly standardized conditions. These factors were sex,...
Differentiated Bayesian Conjoint Choice Designs
Previous conjoint choice design construction procedures have produced a single design that is administered to all subjects. This paper proposes to construct a limited set of different designs. The...
Clustering of dietary variables and other lifestyle factors (Dutch Nutritional Surveillance System).
Hulshof, K F, Wedel, M, Löwik, M R, Kok, F J, Kistemaker, C, Hermus, R J, ...
STUDY OBJECTIVE--The aim was to investigate whether dietary factors cluster in a favourable or unfavourable way and to characterise the groups identified by lifestyle and sociodemographic variables....
