Data (paired comparisons with undecided): CEMS (Community of European management schools)

Description

A survey of 303 students was carried out to examine the student's preferences of 6 universities (London, Paris, Milano, St.Gallen, Barcelona and Stockholm) with a 17 items questionnaire. The first 15 variables indicate the subjects' preferences. For a given comparison the responses are coded as 0 if the first university was preferred, 2 if the second university was preferred and 1 if no decision was made. The variable ENG contains the knowledge of English and the variable SEX contains the gender.
