CITAN is a library of functions useful in - but not
        limited to - quantitative research in the field of
        scientometrics. It contains various tools for preprocessing
        bibliographic data retrieved e.g. from Elsevier's SciVerse
        Scopus and calculating bibliometric impact of individuals.
        Also, many functions dealing with Pareto-Type II (GPD) and
        Discretized Pareto-Type II statistical models are included
        (e.g. Zhang-Stephens and MLE estimators, goodness-of-fit and
        two-sample tests, confidence intervals for the theoretical
        Hirsch index etc.). They may be used to describe and analyze
        many phenomena encountered in the social sciences.
