MathWorks, the company behind Matlab, offers a diverse set of whitepapers showing how engineers are searching for statistical answers. Toyota Racing, for instance, plans its NASCAR entries by analyzing tests in wind tunnels and other labs. Canada's Institute for Biodiagnostics is searching for the best treatment for burns.
There are also a number of open source alternatives, including Octave, Scilab, Sage, and PySci, one of the aforementioned Python libraries. All of these tools help with the complicated statistical analysis that is now becoming common for firms trying to understand what the customer did and what the customer may want to do in the future.
