Description: A user-friendly toolbox for doing the statistical analysis
        of interval-valued responses in questionnaires measuring
        intrinsically imprecise human attributes or features
        (attitudes, perceptions, opinions, feelings, etc.). In
        particular, this package provides S4 classes, methods, and
        functions in order to compute basic arithmetic and statistical
        operations with interval-valued data; prepare customized plots;
        associate each interval-valued response to its equivalent
        Likert-type and visual analogue scales answers through the
        minimum theta-distance and the mid-point criteria; analyze the
        reliability of respondents' answers from the internal
        consistency point of view by means of Cronbach's alpha
        coefficient; and simulate interval-valued responses in this
        type of questionnaires. The package also incorporates some
        real-life data that can be used to illustrate its working with
        several non-trivial reproducible examples. The methodology used
        in this package is based in many theoretical and applied
        publications from SMIRE+CoDiRE (Statistical Methods with
        Imprecise Random Elements and Comparison of Distributions of
        Random Elements) Research Group
        (<https://bellman.ciencias.uniovi.es/smire+codire/>) from the
        University of Oviedo (Spain).
