After last year's record breaking 680 pounds of donated candy, we challenged you to raise the {candy} bar even higher this year...and man did you do
Create a conditional quantile bin plot in SAS
A 2-D "bin plot" counts the number of observations in each cell in a regular 2-D grid. The 2-D bin plot is essentially a 2-D version of a histogram: it provides an estimate for the density of a 2-D distribution. As I discuss in the article, "The essential guide to
Have Trump's tweets-per-day been increasing?
I saw an article that claimed Donald Trump recently tweeted 123 times in one day. This got me wondering how many times he typically tweets during a day, and whether this number has changed over the years. This seems like it might be a good topic to analyze with a
How to deal with well meaning advice
I have a theory about parents (most often mothers, but I might be biased based on my experience!). When we are born, we pick up a suitcase filled with guilt. The contents may shift during flight, but it is almost always full. Some examples are: during pregnancy – whether or not
How many people does it take to publish a book?
The next time you pick up a book, you might want to pause and think about the work that has gone into producing it – and not just from the authors.
Why you should add statistical learning to your machine learning tool kit
Data scientists naturally use a lot of machine learning algorithms, which work well for detecting patterns, automating simple tasks, generalizing responses and other data heavy tasks. As a subfield of computer science, machine learning evolved from the study of pattern recognition and computational learning theory in artificial intelligence. Over time, machine learning has borrowed from many

Math-ing around the Christmas tree: Can the SVD de-noise an image?
Rockin' around the Christmas tree At the Christmas party hop. – Brenda Lee Last Christmas, I saw a fun blog post that used optimization methods to de-noise an image of a Christmas tree. Although there are specialized algorithms that remove random noise from an image, I am not going to
What areas in NC have growing/shrinking population?
I can tell that my area (Wake county, NC) has a growing population, because the traffic keeps getting worse and worse. But it's a little difficult to quantitatively gauge growth by looking at traffic congestion. Therefore let's have a look at a more direct measurement - the actual population data!
Machine Learning with SASPy: Exploring and Preparing your data - Part 3
Parts 1 and 2 of this blog post discussed exploring and preparing your data using SASPy. To recap, Part 1 discussed how to explore data using the SASPy interface with Python. Part 2 continued with an explanation of how to prepare your data to use it with a machine-learning model.
Adding SAS® procedures to the SASPy interface to Python
Bringing the power of SAS to your Python scripts can be a game changer. An easy way to do that is by using SASPy, a Python interface to SAS allowing Python developers to use SAS® procedures within Python. However, not all SAS procedures are included in the SASPy library. So,

Navigating Holiday Gatherings with Moderation in Mind
Who says that holidays have to be stuffed with belly-stuffing traditions? While the average American gains about one to two pounds between Thanksgiving and New Year’s Day, weight gain, indigestion and post-meal sluggishness do not have to be on your wish list.
Swap elements in binary matrices
Binary matrices are used for many purposes. I have previously written about how to use binary matrices to visualize missing values in a data matrix. They are also used to indicate the co-occurrence of two events. In ecology, binary matrices are used to indicate which species of an animal are
When the Holiday Season Collides with Whatever Season of Life You are In
For the last two months I’ve seen commercial after commercial with smiling faces, catchy tunes, and kids running around houses full of good food, presents, and family. This season, we’re encouraged to remember what “matters”. Here’s something else to remember: the goal of these commercials is for the company to
Mapping Antarctica, with a tile-based map
As we're getting into December, and the weather is getting colder, I thought it would be cool to plot some Antarctica data. You might remember I did this about 1.5 years ago, using good-old Proc Gmap, a special projection, and lots of tricky annotation. Well, this time let's use the
