Search for: [Abstract = "The problem of estimation of the partial order on the basis of multiple pairwise comparisons with random errors, in binary and multivalent form is investigated. The estimators are based on the idea of the nearest adjoining order \(see Slater 1961, Klukowski 2011\). Two approaches are examined\: comparisons indicating direction of preference \(binary\) and comparisons indicating difference of ranks \(multivalent\) \- both with possibility of incomparable elements. The properties of estimators and optimization problems for estimates obtaining are similar as in the case of complete relation. The assumptions about distributions of comparisons errors are not the same they comprise the case of incomparable elements."]
