KDNugget's salary survey results have just been released. Salary are higher in 2013. But there were much fewer respondents (383) in 2013 than in 2012 (487). Why?

This example can be used for training purposes, as part of the curriculum to become a data scientist. Here I describe the different steps involved in a typical, real analysis: from understanding the problem (how to forecast meteorite hits) to providing an answer. The Excel spreadsheet with all the details can be downloaded at the bottom of this article.…

I was recently reminded of some work I had completed for the oil and gas industry many years ago and thought it would be useful to share with other analysts/statisticians.
For more general information see a case study I have put onto my personal blog (Offshore Storms Statistics and Oil Rigs).
It was important for the oil… Continue

Ten Predictions for the First Hour of 2020
Good morning. It's January 2, 2020, the first workday of the year. As you drive to the office, the only thing predictive analytics doesn't do for you is steer the car (yet that's coming soon as well).
1. Anti-theft. As you enter your car, a predictive model establishes your…

I have seen lots of heated discussion about the development of big data and its potential value generation. It only generates value when you have a holistic view about your client so that the organization can do something about it. It is like asking for a dates, the more you know about the person, the better.
It is true that market data providers such as Bloomberg, Thomson Reuters etc do a good job in opening up the information about your client external to your organization,… Continue

Guest Post by Stig Eide
Stig Eide showed me a trick for using the Excel web query to look at SAS data. Very clever trick!
Want to view a SAS table in Excel but you don't have the Add-In for Microsoft Office installed? This post describes an alternative method. Excel has a nice feature where you are allowed to query a web page for data. I will describe how you can set up the query against a stored process, and how to pass parameters.
First, you need… Continue

Last October, a colleague and I speculated on how a special, powerful form of predictive analytics would revolutionize presidential campaigning—and, if successful, how it might be poorly received by the public thereafter. In our work, he and I focus more on financial, marketing, and online applications of this technology. But we bet the story would break within politics by 2016 or 2020. Continue

Quite often, while working with Hbase, I used to feel how cool it would be to have a database that can replicate my data to datacenters across the world consistently. So that I can take the pleasure of global availability and geographic locality. And also which will save my data even in case of some catastrophe or… Continue

Hadoop is an open source platform, completely written in Java and distributed under Apache's licence, that allows us to store, manage and process gigantic amounts of data in a highly parallel manner on clusters of commodity machines. It is most suitable for batch processing. People and organizations use Hadoop to build their ETL tools, to perform their BI operations, to do analytics etc.
You can find countless posts on Hadoop over the internet. And most of them are really good. But… Continue

There are lots of topics floating around in the space of data analysis like statistical modeling, predictive modeling. There have always been questions in mind which technique to choose? which is preferred way for data analysis? Some articles and lecture highlight machine learning or mathematical model over statistics modeling limitations. They mention mathematical modeling as a next step of accuracy and prediction. This kind of articles create more questions in mind of naive… Continue
