Since they made marijuana legal in Washington state, I went to one of my favorite restaurants in Seattle, and discovered that they now use marijuana as an ingredient in their famous recipes, in particular in their smoky macarons.
It has absolutely no effect (mind altering) on me, but it also reminded me when I was young and tried a few drugs: none produced anything other than mechanical effect (increased heart beat) on me. Even…Continue

This is data science from the trenches - both a case study, and a tutorial for data sciencist candidates. Here I illustrate how gut feelings, carefully selected data (rather than getting granular data), full understanding of business (horizontal knowledge), high level vision, and outsourcing (to make data science almost free) combined together, makes a data science project…Continue
The discovery process used by data scientists commonly consists of four steps (see also Figure 1):

The field of data science continues to grow, and with it come thought leaders who contribute to the industry through outreach and education. Many of the data science professors teaching today are leaders in the big-data field, speaking at conferences, writing books, and even creating groundbreaking big-data developments themselves. Find out which schools boast the most influential leaders in the data science industry.Continue
Data Scientists Salary Survey shows that industry data scientists are in a sweet spot, especially in US, Canada, and Australia, with average salary $135K. European and Asian data scientists salaries are significantly lower.

In connection with our proposed methodology to create a black-box, automated, easy-to-interpret, sample-based, robust technique called jackknife regression, to be used in small and big data environments by non-statisticians, We offer an award and massive promotion to the successful candidate who

This article discusses a far more general version of the technique described in our article The best kept secret about regression. Here we adapt our methodology so that it applies to data sets with a more complex structure, in particular with highly correlated independent variables.…Continue
This permanent experimental design setting allow you to learn, participate or check out the results at any time, as data is gathered and reported in real time. This article illustrates a few concepts:

All the regression theory developed by statisticians over the last 200 years (related to the general linear model) is useless. Regression can be performed as accurately without statistical models, including the computation of confidence intervals (for estimates, predicted values or…Continue

This is an area of data science that the public is less familiar with. This example involves small data, simulations, and 18 years old crowdsourcing.
It's an attempt to explain the cause of the TWA Flight 800 that exploded near New York on July 17, 1996. I raised the possibility that a potential cause for the Malaysia Airlines flight that went missing last week, was being hit by a missile (accidental or not). Likewise, many people still believe that TWA 800 was destroyed by a…Continue

While companies complain about lack of analytic talent, professionals complain about lack of jobs. Everyone wants to work for Facebook, LinkedIn, Google, Intel, Apple, Twitter or some hot start-up. It creates fierce competition getting a job interview, let alone a job. But companies that do not belong to this circle see very few candidates applying for their data scientist open positions; in addition, they are only hiring what I call technical developers (defined by a narrow set of technical…Continue
