Has anyone ever broken up with you, and left you thinking "Wow, I didn't see that coming!" In hindsight, maybe you could have seen it coming. At least from a statistical perspective. Let's dive into this topic with some lighthearted discussion, and plot some Facebook data... When it comes to
One aspect of high-quality information is consistency. We often think about consistency in terms of consistent values. A large portion of the effort expended on “data quality dimensions” essentially focuses on data value consistency. For example, when we describe accuracy, what we often mean is consistency with a defined source
This is the 2nd installment of the "Getting Started" series, and the audience is the user who is new to the SG Procedures. It is quite possible that an experienced users may also find some useful nuggets here. One of the most popular and useful graph types is the Bar
In the DATA step, the WHERE statement and the IF statement (a.k.a. the "subsetting IF") have similar functions. In many scenarios, they produce identical results. But new SAS programmers are taught early on that these two statements work very differently, and in important ways. To understand the differences, it helps
Using the DATASETS procedure, we can easily modify SAS variable attributes such as name, format, informat and label: proc datasets library=libref; modify table_name; format var_name date9.; informat var_name mmddyy10.; label var_name = 'New label'; rename var_name = var_new_name; quit; We cannot, however, modify fixed variable attributes such as variable type
In my previous post, I showed you how to change the titles in graphs produced by analytical procedures; today I will show you how to remove subtitles that procedures display on some output pages. The following step creates output that contains a SAS title ('Illustrate the CIF Plot'), a PROCTITLE

Teacher preparation programs have received some pretty harsh criticism in recent years. For example… “If there was any piece of legislation that I could pass it would be to blow up colleges of education.” –Reid Lyon, National Institute of Health “By almost any standard, many if not most of the
Maybe programming isn’t quite as dangerous as a lightsaber battle, but if you think using SAS to turn data into action feels a little bit like magic, you should know that nobody is better at harnessing “the Force” of DS2 than SAS Jedi Mark Jordan. Mark has a resume that
If you consider yourself as a visualization expert, you strive to create graphs that set you apart from the data analysts and statisticians. Graphs that merely plot the data in a clear/concise manner aren't enough for you. You want your graphs to also be intuitive, easy to read, and provide
Our world is now so awash in data that many organizations have an embarrassment of riches when it comes to available data to support operational, tactical and strategic activities of the enterprise. Such a data-rich environment is highly susceptible to poor-quality data. This is especially true when swimming in data lakes –
People say that the world has changed, but I think it'd be more accurate to say that people that have changed the world. Social media, big data, big analytics, internet of things … whether you're an executive, a data scientist, or a student, when you hear these buzzwords, you have
