Someone sent me some questions by email, and I decided to answer some of them here. How important is it that I know and understand the underlying mathematical framework to forecasting methods?

I’ve been having discussions with colleagues and university administration about the best way for universities to manage home-grown software.

Some new websites are being established offering “market places” for data science. Two I’ve come across recently are Experfy and SnapAnalytx. Experfy provides a way for companies to find statisticians and other data scientists, either for short-term consultancies, or to fill full-time positions. They describe their “providers” as “Data Engineers, Data Scientists, Data Mining Experts, Data Analyst/Modelers, Big Data Solutions Architects, Visualization Designers, Statisticians, Applied Physicists, Mathematicians, Econometricians and Bioinformaticians.”…
Earo Wang recently interviewed me for the Chinese website Capital of Statistics. The English transcript of the intervew is on Earo’s personal website. This is the third interview I’ve done in the last 18 months. The others were for: Data Mining R...
I’ve been getting emails asking questions about my upcoming course on Forecasting using R. Here are some answers. Do I need to use the Revolution Enterprise version of R, or can I use open-source R?
