    • DISTANCE MEASURES IN AGGREGATING PREFERENCE DATA 

      Zaborski, Artur (Wydawnictwo Uniwersytetu Łódzkiego, 2014)
      The aim of this paper is to present aggregation methods of individual preferences scores by means of distance measures. Three groups of distance measures are discussed: measures  which use preference distributions for all ...
    • Geometrical Presentation of Preferences by Using Profit Analysis and R Program 

      Zaborski, Artur; Pełka, Marcin (Wydawnictwo Uniwersytetu Łódzkiego, 2013)
      PROFIT is a kind of external vector analysis of preference mapping. It is a combination of multidimensional scaling and multiple regression analysis. PROFIT takes as input both a configuration of stimulus points and a ...
    • Geometrical presentation of preferences by using unfolding models 

      Zaborski, Artur (Wydawnictwo Uniwersytetu Łódzkiego, 2010)
      Analiza unfolding jest szczególnym przypadkiem skalowania wielowymiarowego. Zakłada ona, że respondenci postrzegają wybrane obiekty w tej samej przestrzeni, ale różnią się w ocenie ważności ich poszczególnych atrybutów. ...
    • Gravity Unfolding Analysis for Asymmetric Similarities Matrix 

      Zaborski, Artur (Wydawnictwo Uniwersytetu Łódzkiego, 2013)
      The multidimensional unfolding analysis which uses in the structure the gravity function allows consideration and analysis of additional factors (such as market share or brand loyalty), which affect the assessments of ...
    • The Influence of Triad Selection on the Preference Scaling Results 

      Zaborski, Artur (Wydawnictwo Uniwersytetu Łódzkiego, 2017)
      In the method of triads for a set of n objects all three element sets of objects are presented to the respondents. A respondent is asked to pick out the most similar and the least similar pair. The method of triads, despite ...
    • The Presentation of Changes in Preferences by Dynamic Scaling 

      Zaborski, Artur (Wydawnictwo Uniwersytetu Łódzkiego, 2016)
      Dynamic scaling is a set of methods in which the geometrical representation of the similarity data for T different time periods is made. This article presents the use of two-dynamic scaling methods for studying changes in ...
    • Switch Preference Analysis by the Drift Vectors Method 

      Zaborski, Artur (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
      The matrix of switch preference data (e.g. one’s preference for brand j, given that one has already defined his/her first choice for brand i) is not symmetric. The averaging of appropriate off-diagonal proximity entries ...
