I’ve done one more MOOC class by Coursera. This one was on pretty hot topic — Data Analysis/Statistics. Well, it was not related to theoretical issues, but rather fit to pure technical aspect. It was an introduction to the R system and programming. R is a well-done alternative to MathLab, or to its data processing part, at least. Actually, I’ve been using R on both Windows and OSX. As MathLab, R is also useful for modelling and working with relatively small amounts of data. On the other hand, there are BigData volumes in real world. So, R or Mathlab is not enougn for today. Generally, you need some BigData technology like Hadoop to implement your model in production.
