Stata Student Version

Will 2. 01. 5 be the Beginning of the End for SAS and SPSSSince this was originally published in 2. Ive collected new data that renders this article obsolete. You can always see the most recent data here. Bob MuenchenLearning to use a data analysis tool well takes significant effort, so people tend to continue using the tool they learned in college for much of their careers. As a result, the software used by professors and their students is likely to predict what the next generation of analysts will use for years to come. I track this trend, and many others, in my article The Popularity of Data Analysis Software. In the latest update 41. Students currently enrolled at degreegranting institutions may purchase Stata at the prices listed below. Proof of student status a copy of your university ID card. EViews Student Version offers the easeofuse and power of EViews at a low cost for classroom use.

That was based on the data shown in Figure 7a, which I repeat here Lets take a more detailed look at what the future may hold for R, SAS and SPSS Statistics.

The forecast has taken a logical approach of focusing on the steeper decline from 2. Rosario Vampire Sims 3. SPSS will see use in scholarly publications. However the part of the graph that I find most interesting is the shift from 2. SPSS use still declining but at a much slower rate. Any forecasting book will warn you of the dangers of looking too far beyond the data and I think these forecasts do just that. The 2. 01. 5 figure in the Popularity paper and in the title of this blog post came from an exponential smoothing approach that did not match the rate of acceleration as well as the ARIMA approach does. Colbert Forecasting. While ARIMA forecasting has an impressive mathematical foundation its always fun to follow Stephen Colberts approach go from the gut. So now Ill present the future of analytics software that must be true, because it feels so right to me personally. This analysis has Colberts most important attribute truthiness. The growth in Rs use in scholarly work will continue for two more years at which point it will level off at around 2. This growth will be driven by. The continued rapid growth in add on packages Figure 1. The attraction of Rs powerful language. The near monopoly R has on the latest analytic methods. Its free price. The freedom to teach with real world examples from outside organizations, which is forbidden to academics by SAS and SPSS licenses it benefits those organizations, so the vendors say they should have their own software license. What will slow Rs growth is its lack of a graphical user interface that Is powerful. Is easy to use. Provides journal style output in word processor format. Is standard, i. e. Microsoft Office Enterprise Edition By Yahoo. The One to Use. Is open source. While programming has important advantages over GUI use, many people will not take the time needed to learn to program. Therefore they rarely come to fully understand those advantages. Conversely, programmers seldom take the time to fully master a GUI and so often underestimate its capabilities. Regardless of which is best, GUI users far outnumber programmers and, until resolved, this will limit Rs long term growth. There are GUIs for R, but so many to choose from that none becomes the clear leader Deducer, R Commander, Rattle, Red R, at least two from commercial companies and still more here. If from this GUI chaos a clear leader were to emerge, then R could continue its rapid growth and end up as the most used package. The use of SAS for scholarly work will continue to decline until it matches R at the 2. This is caused by competition from R and other packages notably Stata but also by SAS Instutes self inflicted GUI chaos. For years they have offered too many GUIs such as SASAssist, SASInsight, IMLStudio, the Analyst application, Enterprise Guide, Enterprise Miner and even JMP which runs SAS nicely in recent versions. Professors looking to meet student demand for greater ease of use could not decide what to teach so they continued teaching SAS as a programming language. Even now that Enterprise Guide has evolved into a good GUI, many SAS users do not know what it is. If SAS Institute were to completely replace their default Display Manager System with Enterprise Guide, they could bend the curve and end up at a higher level of perhaps 2. The use of SPSS for scholarly work will decline only slightly this year and will level off in 2. The people who needed advanced methods and were not happy calling R functions from within SPSS have already switched to R or Stata. The people who like to program and want a more flexible language than SPSS offers have already switched to R or Stata. The people who needed a more advanced GUI have already switched to JMPThe GUI users will stick with SPSS until a GUI as good or close to as good comes to R and becomes widely accepted. At The University of Tennessee where I work, thats the great majority of SPSS users. Statas growth will level off in 2. The other packages shown in Figure 7b will also level off around the same time, roughly maintaining their current place in the rankings. A possible exception is JMP, whose interface is radically superior to the the others for exploratory analysis. Its use could continue to grow, perhaps even replacing Stata for fourth place. The future of Enterprise Miner and SPSS Modeler are tied to the success of each companys more mainstream products, SAS and SPSS Statistics respectively. Use of those products is generally limited to one university class in data mining, while the other software discussed here is widely used in many classes. So there you have it the future of analytics revealed. No doubt each reader has found a wide range of things to disagree with, so I encourage you to follow the detailed blog at Librestats to collect your own data from Google Scholar and do your own set of forecasts.
