Notes
Comparing with similar KDnuggets Polls
in 2013: What programming/statistics languages you used for analytics / data mining in 2013, and
2012: What programming/statistics languages you used for analytics / data mining in the past 12 months?
we note several changes and trends.
1. A big increase in SAS user participation in 2014, perhaps partly driven by a change in KDnuggets readers composition, perhaps partly by increased visibility of this poll among SAS users.
SAS voters also had a high percentage of "lone" votes - in 2014, 58% of them said they used only SAS, compared to 26% in 2013. The number of "lone" votes in 2014 was 20.5% for R, 14% for Python, and 4.5% for SQL.
2. Consolidation among top 4 languages: R, SAS, Python, and SQL, and decline in usage of less popular languages for data mining: Java, Unix shell, MATLAB, C/C++, Perl, Octave, Ruby, Lisp, F.
3. Languages with the highest growth in 2014 were
- Julia, 316% growth, from 0.7% share in 2013 to 2.9% in 2014
- SAS, 76% growth, from 20.8% in 2013 to 36.4% in 2014
- Scala, 74% growth, from 2.2% in 2013 to 3.9% in 2014
- F#, 100% decline, from 1.7% share in 2013 to zero in 2014
- C++/C, 60% decline, 9.3% in 2013 to 3.6% in 2014
- GNU Octave, 57% decline, from 5.6% in 2013 to 2.4% in 2014
- MATLAB, 50% decline, from 12.5% in 2013 to 6.3% in 2014
- Ruby, 44% decline, from 2.2% in 2013 to 1.3% in 2014
- Perl, 41% decline, from 4.5% in 2013 to 2.6% in 2014
Among other programming languages William Dwinnell mentioned Compiled BASIC (PowerBASIC).
