StatsDirect is a statistical software package designed for biomedical, public health, and general health science uses. The second generation of the software was reviewed in general medical[1] and public health journals.[2]
StatsDirect's interface is menu driven and has editors for spreadsheet-like data and reports. The function library includes common medical statistical methods that can be extended by users via an XML-based description that can embed calls to native StatsDirect numerical libraries, R scripts, or algorithms in any of the .NET languages (such as C#, VB.Net, J#, or F#).[3]
Common statistical misconceptions are challenged by the interface. For example, users can perform a chi-square test on a two-by-two table, but they are asked whether the data are from a cohort (perspective) or case-control (retrospective) study before delivering the result. Both processes produce a chi-square test result but more emphasis is put on the appropriate statistic for the inference, which is the odds ratio for retrospective studies and relative risk for prospective studies.[4]
