CITAN is a library of functions useful in - but not
        limited to - quantitative research in the field of
        scientometrics. It contains various methods for pre-processing
        bibliometric data retrieved e.g. from Elsevier's SciVerse
        Scopus and calculating 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.
