Spotting a misleading chart
Everyone loves a good conspiracy theory - hopefully you'll enjoy mine about the number of US E1 visas! I was perusing some of the US government charts, and found one on US immigration visas that caught my attention. It was a 3D bar chart, and since I always mistrust 3D

On the number of permutations supported in SAS software
There's "big," and then there is "factorial big." If you have k items, the number of permutations is "k factorial," which is written as k!. The factorial function gets big fast. For example, the value of k! for several values of k is shown in the following table. You can

When art and analytics collide
The best graphs are both beautiful and informative - a smooth blend of art and analytics. But more often than not, the two collide rather than blending smoothly... Here is a link to a artistic infographic I recently saw posted by Vendavo on twitter. Their message (80% of your profit is generated

SAS MDM new release brings harmony to big data discord
I've been in many bands over the years- from rock to jazz to orchestra - and each brings with it a different maturity, skill level, attitude, and challenge. Rock is arguably the easiest (and the most fun!) to play, as it involves the least members, lowest skill level, a goodly amount of drama, and the
EMC and SAS redefine big data analytics with the data lake
Adoption of Hadoop, a low-cost open source platform used for processing and storing massive amounts of data, has exploded by almost 60 percent in the last two years alone according to Gartner.

Vectors that have a fractional number of elements
The title of this article makes no sense. How can the number of elements (in fact, the number of anything!) not be a whole number? In fact, it can't. However, the title refers to the fact that you might compute a quantity that ought to be an integer, but is

Euro vs Dollar exchange rate: An historic event?
I recently read a Washington Post article about the euro versus the dollar, and I wanted to analyze the data myself to see whether the article was simply stating the facts, or "sensationalizing" things.

How does an insurer prioritize all these seemingly competing goals and create sustainable competitive advantage. One answer is analytics.

How to reverse graph axes in SAS Visual Analytics
It may never crossed your mind, but there are real-life cases when reversing graph axes make sense. For example, when Y-axis represents a depth under the sea level or depth of oil well drilling, it makes perfect sense to have zero on top and positive numbers increasing from top down.

Stability and predictability: The alternative selling points for your data quality vision?
One thing that always puzzled me when starting out with data quality management was just how difficult it was to obtain management buy-in. I've spoken before on this blog of the times I've witnessed considerable financial losses attributed to poor quality met with a shrug of management shoulders in terms

Finding observations that match a target value
Imagine that you have one million rows of numerical data and you want to determine if a particular "target" value occurs. How might you find where the value occurs? For univariate data, this is an easy problem. In the SAS DATA step you can use a WHERE clause or a
When the going gets tough, the tough use analytics
When do analytics really provide value? All the time, of course. However, one of the best times for analytics to prove their value is when you are asked to do more with less. Often, the reason we are asked to do more with less is because of an economic downturn
