The art and (data) science of leveraging economic bubbles

I have played with a few bubbles - stock market, real estate - and it seems that they are relatively predictable, with their growth being spectacular in their last few months. While it is difficult to identify when a bubble starts to form, it is my rule of thumb that you can expect to extract on average 1/3 of a bubble's energy and turn it into profit. Another rule of mine is to sell if your asset's value increased by more than 200% within a four year time period. I am wondering if some…

What statisticians think about data scientists

Interesting to read what some statisticians write about data science, on the American Statistical Association (ASA) blog. Most of us don't care about our job title - there are so many breeds of statisticians and data scientists after all - and they do overlap to some extent. While I was once a statistician, I now call myself data scientist or…

A subset (2,000 articles) is…
