Preferences of 303 students from WU Wien for different CEMS universities.
data("CEMSChoice")A data frame containing 303 observations on 10 variables.
Paired comparison of class paircomp.
Preferences for all 15 paired comparisons from 6 objects:
London, Paris, Milano, St. Gallen, Barcelona, Stockholm.
Factor coding main discipline of study: commerce, or other (economics, business administration, business education).
Factor coding knowledge of English (good, poor).
Factor coding knowledge of French (good, poor).
Factor coding knowledge of Spanish (good, poor).
Factor coding knowledge of Italian (good, poor).
Factor. Was the student working full-time while studying?
Factor coding gender.
Factor. Does the student intend to take an international degree?
Paired comparison of class paircomp.
This is like preference but the comparisons between Barcelona
an Stockholm are (erroneously) reversed, see below.
Students at Wirtschaftsuniversität Wien (https://www.wu.ac.at/) can study abroad
visiting one of currently 17 CEMS universities (Community of European Management
Schools and International Companies). Dittrich et al. (1998) conduct and analyze
a survey of 303 students to examine the student's preferences for 6 universities:
London School of Economics, HEC Paris, Università Commerciale Luigi Bocconi (Milano),
Universität St. Gallen, ESADE (Barcelona), Handelshögskolan i Stockholm.
To identify reasons for the preferences, several subject covariates (including
foreign language competence, gender, etc.) have been assessed. Furthermore,
several object covariates are attached to preference (and preference1998):
the universities' field of specialization (economics, management science, finance)
and location (Latin country, or other).
The correct data are available in the online complements to Dittrich et al. (1998).
However, the accompanying analysis was based on an erroneous version of the data in which the
choices for the last comparison pair (Barcelona : Stockholm) were accidentally reversed. See the
corrigendum in Dittrich et al. (2001) for further details. The variable preference
provides the correct data and can thus be used to replicate the analysis from the
corrigendum (Dittrich et al. 2001). For convenience, the erroneous version is
provided in preference1998 which can therefore be used to replicate the
(incorrect) original analysis (Dittrich et al. 1998).
