Fuzzy data such as marks, scores, verbal evaluations, imprecise  observations, experts' opinions and grey tone pictures, are quite  common. In Fuzzy Data Analysis the authors collect their recent  results providing the reader with ideas, approaches and methods for  processing such data when looking for sub-structures in knowledge  bases for an evaluation of functional relationship, e. g. in order to  specify diagnostic or control systems. The modelling presented uses  ideas from fuzzy set theory and the suggested methods solve problems  usually tackled by data analysis if the data are real numbers. 
  Fuzzy Data Analysis is self-contained and is addressed to  mathematicians oriented towards applications and to practitioners in  any field of application who have some background in mathematics and  statistics.
