Stan has the ability to become the de facto Bayesian modeling software. Designed by thought leader Andrew Gelman and a growing, enthusiastic community, Stan possesses much promise. The language architecture promotes cross‐compatibility and extensibility, and the general‐purpose posterior sampler with innovative diagnostics appeals to novice and advanced modelers alike. Further, to our knowledge, Stan is the only general‐purpose Bayesian modeler that scales to thousands of parameters – a boon for big data analytics.
5 The Future of Statistical Computing
Two key drivers will dictate statistical software moving forward: (i) Increased model complexity and (ii) increased data collection speed and sheer size (big data). These two factors will require software to be highly flexible – the languages must be easy to work with for small‐to‐medium data sets/models, while easily scaling to massive data sets/models. The software must give easy access to the latest computer hardware (including GPUs) and provide hassle‐free parallel distribution of tasks. To this end, successful statistical software must feature compiled/optimized code of the latest algorithms, parallelization, and cloud/cluster computing support. Likely, one tool will not meet all the demands, and therefore cross‐compatibility standards must be developed. Moreover, data visualization will become increasingly important (including virtual reality) for large, complex data sets where conventional inferential tools are suspect or without use.
The advantages of open‐source, community‐based development have been emphasized throughout – especially in the scholarly arena and with smaller businesses. The open‐source paradigm enables rapid software development with limited resources. However, commercial software with dedicated support services will appeal to certain markets, including medium‐to‐large businesses.
6 Concluding Remarks
We attempted to evaluate the current statistical software landscape. Admittedly, our treatment has been focused by our experience. We have, however, sought to be fair in our appraisal and provide the burgeoning statistical programmer the information required to make strong tool selection choices and increase their performance. We begin by in‐depth discussions of the most‐popular statistical software, followed by brief descriptions of many other noteworthy tools, and then finally highlighted a handful of emerging statistical software. We hope that this organization is useful, but note that it is solely based on our experiences and informal popularity studies [4]. We also provided a limited prognostication with regard to the statistical software future by identifying issues and applications likely to shape software development. We realize, of course, that the future is usually full of surprises and only time will tell what actually occurs.
