<quote>We have to notice that nearly no one high in business now or on the way to being high in business knows more than just
some elementary applied statistics, from long ago, that they never understood very well, never really used, and was
likely poorly taught. Also they have not seen much of significance in business from anything at all serious in
statistics. They know about the importance of computing, the Internet, and maybe some of assembly line robots, supply
chain optimization, comparisons among planes, trains, trucks, biomedical research, even efforts in applied nuclear
fusion, but they nearly never attribute significant importance to statistics.</quote>
You've never worked in finance, have you? Modern economics, especially the portions dealing with finance, is
indistinguishable from applied statistics. The Black-Scholes option pricing formula that is at the heart of almost all
trading algorithms is statistical. VaR and other risk metrics all rely heavily on statistics. Now, its an open
question as to whether such a reliance on statistical methods is a good thing for the industry. However, you cannot say
that managers in finance companies don't appreciate statistics. They appreciate it very much, since those statistical
models determine their bonus at the end of the year.
- HilbertSpace 16y agoFrom all I know, your rosy picture for statistics, etc. on Wall Street is not realistic. The Black-Scholes option pricing formula is simple to program and has been programmed many times by people with essentially no knowledge of statistics -- or stochastic differential equations or the connections between probability theory and potential theory. I could go down a long list of evidence, but I will mention just two points: I still have a letter back to me from Fisher Black saying that he saw no such opportunities. Jim Simons has stated that he doesn't use math in his work.
