Description: Frequentist sequential meta-analysis based on 'Trial
        Sequential Analysis' (TSA) in programmed in Java by the
        Copenhagen Trial Unit (CTU). The primary function is the
        calculation of group sequential designs for meta-analysis to be
        used for planning and analysis of both prospective and
        retrospective sequential meta-analyses to preserve type-I-error
        control under sequential testing. 'RTSA' includes tools for
        sample size and trial size calculation for meta-analysis and
        core meta-analyses methods such as fixed-effect and
        random-effects models and forest plots. TSA is described in
        Wetterslev et. al (2008) <doi:10.1016/j.jclinepi.2007.03.013>.
        The methods for deriving the group sequential designs are based
        on Jennison and Turnbull (1999, ISBN:9780849303166).
