A Data Science Central Community
The on-going Big Data media hype stirs up a lot of passionate voices. There are naysayers ("it is nothing new"), doomsayers ("it will disrupt everything"), and soothsayers…Continue

Over 100 years ago, the great science fiction writer H. G. Wells was credited with saying, "Statistical thinking will one day be as necessary for efficient citizenship as the ability to read or write." It is clear that this statement is probably more true today than ever, as Big Data and Analytics are paraded before every aspect…Continue
Here we discuss two types of widespread analytic handicaps: individuals affected by poor analytics, committing financial suicide but impacting very few people, and government or corporate analytic failure negatively impacting millions of people.…Continue
Have you looked at the syllabus of the Finance class on financial modeling at the University? It is outdated: It teaches you how to do modeling on one single company, if possible multiple years of the same company. To any Analytics professional, it is a joke. It's like having a table with a few records - one record for each year. Let's wake up and go for a change:
1. Pour the whole world of companies into research: instead of putting the projection of financial data in different…Continue
Marketing analytics has been around for so long that people have now started talking about sub - areas such as CRM analytics, forecasting, marketing supply chain, perishable retail analytics and so on. However, before you discredit this to be another blog reiterating the importance of analytics, I would like to clarify that this is rather about the challenges an analytics company faces in marketing analytics solutions.
On the surface, selling analytics seems to be simple... who…Continue

Can we detect a crime before it occurs?
Imagine you could predict that a crime would happen at a certain place and time…
Now, imagine that you could also predict who the possible suspects were, where they came from, and what their motives were…
Sounds like science fiction? Well… it may be… but the emphasis is on the “science” rather than the “fiction”, and we even have a name for it: Predictive Forensics.
Predictive Forensics is an analytics discipline that attempts…Continue

When you invest the time to read a book, you're investing a lot more than the $17 to buy it.
Many ask whether my book, Predictive Analytics: The Power to Predict Who Will Click, Buy, Lie, or Die, is at the right level for their needs. Is it too advanced? (Quick answer: definitely not.) Will it instruct me on how to execute on predictive analytics? (Not directly – it is an industry primer rather than a…Continue

This is a follow up to our article on Structuredness coefficient to find patterns and associations, featuring an image (animated gif) with rotating dots that simulate waves. I went one step further here, to create a new data video, where rotating points (by accident) simulate…Continue
We are investigating a metric that measures the presence or absence of a structure or pattern in data sets. The purpose is to measure the strength of the association between two variables, and generalizes our modern correlation coefficient in a few ways:…Continue

Trailhead parking lots are notorious for crime activity - including from bears. These remote, un-patrolled locations, hidden in dense forests, attract all sorts of bad guys. One original crime is thieves stealing the park fees paid by hikers. These fees consist of $5 bills inserted by trail users (hikers) in an envelope, and dropped in a locked mailbox at the trailhead. These wooden boxes are easy to break and…Continue
I read about this from some other source (which I forgot) and would like to attribute this idea to the original author. As an industry practitioner, I do not feel ashamed of copying people's idea at work.
The subject is indeed a challenge for us as an Anlaytics geeks. You (our internal client) came with a problem and we solved your problem, period. No, the best solution is to be able to sell your analytic project that can benefit your internal client's client.

This blog post is to retract an aspect of a story about Chase Bank that I reported in my book, Predictive Analytics: The Power to Predict Who Will Click, Buy, Lie, or Die (published by Wiley, February 2013).
Although predictive analytics professionals usually tell accurate stories about their projects, sometimes the information that comes from human beings is less reliable than the data driven systems they…Continue

Many interesting questions came up in the NIST Definitions and Taxonomy Big Data group meeting today. Brilliant minds are hard at work to stabilize the language around Big Data, but some fundamental questions have been posed that the marketplace seems to believe we have already solved.
