Abstract
In the paper we propose a very simple method for the analysis of dependencies between consecutive observations of a short time series when individual observations are imprecise (fuzzy). For this purpose we propose to apply a fuzzy version of the Kendall’s τ statistic. The proposed methodology can be used for the analysis of a short series of opinion polls when answers of individual respondents are presented in an imprecise (fuzzy) form.
