Last week I showed how to use the simple bootstrap to randomly resample from the data to create B bootstrap samples, each containing N observations. The simple bootstrap is equivalent to sampling from the empirical cumulative distribution function (ECDF) of the data. An alternative bootstrap technique is called the smooth
Die Fortschritte im Bereich Analytics sind rasant. Während vor wenigen Jahren nur wenige Experten Themen wie Machine Learning, Data Mining oder Cognitive Computing diskutierten, beschäftigen sich jetzt auch Nicht-Mathematiker und Fachbereiche mit diesen Begriffen und versuchen, diese einzuordnen. In meinen Gesprächen mit CIOs, zunehmend auch mit Chief Digital Officers, treffe
El Chief Analytics Officer (CAO) es una posición directiva dentro de las compañías, cuya función principal es el análisis estratégico de los datos empresariales.

Foster youth present a unique challenge to educators. Probably the most famous former foster care child in the world right now is Simone Biles, already one of the more formidable and successful athletes in the history of American sports. As a big fan of women’s gymnastics, Biles has thrilled me with her accomplishments.
"Tap into all your demand signals. Organize. Visualize. Analyze. Predict. Orchestrate. Optimize." The availability and collection of data are compelling companies to invest in demand signal management solutions to take advantage of the vast amount of information to support their planning processes. However, many have not gotten the return on
Since this is an election year, I've been scrutinizing the voter registration data. One thing that surprised me is there are more female voters registered in NC than males. I wondered if this was consistent across all 100 counties, and created some charts to help visualize the data... First I went
Last week I was visiting San Diego for the SANDS conference. I always enjoy this conference as I get to interact closely with the users to hear of their pains and innovative solutions to creating Clinical Graphs. In the conference Ed Barber asked about displaying A1c data along with some
Reference lines on a visualization are used to help identify goals or targets, acceptable or unacceptable ranges, etc; basically any metric that puts a frame of reference around the values on the visualization. The Percent of Total of a metric is used to help identify a part-to-whole relationship. It answers
Companies launch initiatives to upgrade or improve their sales & operations planning and demand planning processes all the time, but many fail to deliver the results they should. Has your forecasting operation fallen short of expectations? Do you struggle with "best practices" that seem incapable of producing accurate, useful results?
What does it really mean when we talk about the concept of a data asset? For the purposes of this discussion, let's say that a data asset is a manifestation of information that can be monetized. In my last post we explored how bringing many data artifacts together in a

Last week I showed some features of SAS formats, including the fact that you can use formats to bin a continuous variable without creating a new variable in the DATA step. During the discussion I mentioned that it can be confusing to look at the output of a formatted variable
Has there ever been an app that’s captured the world’s imagination as quickly as Pokemon Go? The usage statistics are mind-blowing, and whether or not the world has reached “peak Pokemon Go” yet, this will doubtless be a short-lived fad. But this could be the app that brings augmented reality and
There's an old expression "if you can't measure it, you can't manage it" - and while that expression probably isn't universally true (as pointed out in this interesting article), I think having a way to quantify your stress could be useful. I recently read an interesting article about the Holmes-Rahe Life
A colleague approached me with this very important business problem: Every Friday at SAS HQ, SAS cafe staff provides a breakfast goodie in our breakrooms. Often the supplied goodie is delicious, but sometimes it's more...well...healthy. I want to know whether I should eat my breakfast before I leave home on
Asking about the benefits of artificial intelligence and machine learning reminds me a little of the transition to suitcases with wheels. Do you remember lugging around those old suitcases? If not, good for you - this original advertisement from US Luggage will take you back! Thank Bernard Sadow for persistence with his
Data monetization, at its simplest, is the process of turning data into bottom-line value for a company -- often through improving efficiency and/or customer experience, and building customer loyalty as a result. This may sound simple, but in practice, it’s anything but. Good data, advanced analytics and real-time decision making
Machine learning applications for NBA coaches and players might seem like an odd choice for me to write about. Let us get something out of the way: I don’t know much about basketball. Or baseball. Or even soccer, much to the chagrin of my friends back home in Europe. However,
As a SAS administrator, you may face situations where you need to locate content that has been modified in the system since a given point in time. If the system has many content developers, discovering all of the folders, libraries, tables, reports, explorations, and similar items that have been modified can be
Where is solar and wind power generated in the US? Let's visualize this data on a map... I recently saw the following map on the metricmaps.org website. It caught my attention because it looks like North Carolina has a lot of solar power plants, whereas our neighboring states have very few.

If your enterprise is working with Hadoop, MongoDB or other nontraditional databases, then you need to evaluate your data strategy. A data strategy must adapt to current data trends based on business requirements. So am I still the clean-up woman? The answer is YES! I still work on the quality of the data.
I recently returned from my annual family beach vacation. It’s my family and my husband’s family, so around 35 or 40 of us in all. As you can imagine, there is a lot of beach time, huge dinners, and a lot of drinking.
A common question is "how do I compute a bootstrap confidence interval in SAS?" As a reminder, the bootstrap method consists of the following steps: Compute the statistic of interest for the original data Resample B times from the data to form B bootstrap samples. How you resample depends on

When I think of the Western Users of SAS Software conference, I think of my first event in 1994. I was just starting to learn SAS and wanted to meet others in my region who were also excited about the software. Meeting and discussing SAS topics face to face at the

I ran across a map recently that seemed to show a lot of US states are primarily coal-powered. The map was a little difficult to read, so I decided to give it a SAS makeover ... Before we get started, here's a picture my friend David took of the Shearon Harris Nuclear Power
