When this post appears, I will be on my way to Seattle. Maybe I will meet some of you there. You can still register here. I held onto this tip from a reader for a while. I think it came...

Myths of Data Science and Analytics

April 11, 2016
By

Last week, I gave some brief remarks at the INFORMS New York Metro Student-Practitioner Forum (link), attended by a large group of enthusiastic students eager to enter the field of data science and analytics. (By the way, if you are at the INFORMS Analytics Conference in Orlando, come and find me. I am speaking on Ethics on Tuesday morning.) I told the students that it is not too early to…

How to get fired, the data scientist edition

Investors of Herbalife (HLF) are owed a full explanation of the metrics disaster that the management disclosed suddenly to the SEC last week. As a regulator, the SEC should be requesting much more information about what happened. (Click on the 8K filed in March 2016. Here is the LA Times article.) On Feb 25, Herbalife management held an earnings call to discuss 2015 4th quarter and full year results. Investors…

Know your data 18: your location is our product

In the last post in the Know Your Data series, I discussed how Uber can use its vast database of your personal trips against your personal interests. (This does not preclude the possibility that they use the data for your benefit.) It turns out that something more ominous is at foot… a number of news outlets have just published investigative reports about a company known as Vigilant Solutions (EFF, The…

The failure to replicate scientific findings

January 19, 2016

Andrew Gelman and I have published a piece in Slate, discussing the failure to replicate scientific findings, using the recent example of the so-called power pose. The idea of the "power pose" is that people develop psychological and hormonal changes by making this "power pose" before walking into business meetings, whereupon these changes make them more powerful. As you often read here and at Gelman's blog, the fact that someone…

Know your data 17: when other people can track your Uber location

The news is out that Uber got fined by the New York Attorney General's office for data breaches and privacy concerns. The headline writer for ZDNet nailed this one: "Uber fined peanuts in God View surveillance" (link). And the sub-lead has the kicker: "For a company with a valuation of over $50 billion, a $20,000 fine over user data protection is laughable." This settlement tells us one of the following…

It’s difficult for journalists to get statistics right: the real estate edition

December 16, 2015
By

A friend pointed me to a good article on the buoyant real-estate market in Boston (link). The journalist tells us the median home sale price in Suffolk County has gone up 31 percent in the five years since the 2010 crash. The article makes some excellent points. When it comes to talking about median house prices, it fails basic statistics. Here is a quote (maybe a misquote) from Barry Bluestone,…

Enhanced tables, and supercharged spreadsheets with in-cell tech

Old-timer Chris P. sent me to this Bloomberg article about Vanguard ETFs and low-cost funds (link). The article itself is interesting, and I will discuss it on the sister blog some time in the future. Chris is impressed with this...
