In clinical trials, a waterfall plot is often used to indicate how patients in the study responded to treatment. In oncology trials, the response variable might be the percent change in the size of a tumor from the individual's baseline value at the start of the trial. The percent change
Analytics as it pertains to the employees and the workforce is taking the industry by storm. Recently, I read an article in the Wall Street Journal about how companies are harnessing the power of analytics to help them identify staff who are likely to leave. In the past few weeks
In a previous post, I discussed how hospitality marketers can gain a complete picture of their guests and understand guest behavior with analytics. In this post, I will explore what you can do once you have a complete picture of your guests. Today’s operating environment presents a set of challenges
Data about the monthly wait times at VA facilities in the US are now available, but it's a bit overwhelming to try to analyze them in tabular form - plotting the data on a map made it a lot easier!... Here in the US, when our soldiers finish their commitment in
There is no doubt that analytics is an overused and often abused term. So what does really analytics means? In part 2 of a series of articles on the analytical lifecycle, this blog will highlight some of the common and emerging techniques used to analyze data and build predictive models

Oil is bouncing around the $50 range as the market adds and loses value with each new headline, from potential new Iranian exports after the nuclear talks to the slowest month of inventory builds at Cushing since Thanksgiving. The US rigcount is down nearly 23 percent year-over-year, but the rate
With all the enhancements in demand management over the past decade, companies are still faced with challenges impeding the advancement of demand-driven planning. Many organizations are struggling with how to analyze and make practical use of the mass of data being collected and stored. Others are perplexed as how to
I watched with wonder as each of my daughters learned how to "tell time." Early in their primary school careers, they brought home worksheets that featured clock faces with big-hand/little-hand configurations that they had to decipher, and exercises that asked them to draw the hands as they should appear given
With so much information available about high-performance analytics, business intelligence and visual analytics, it can be difficult to know exactly where to begin, especially if you don’t have a team of statisticians standing by. I'm frequently asked by customers who hope to take advantage of analytics how to get started. How do
Has this year's flu been better or worse than you thought it would be? There are a lot of factors that help determine whether or not you're likely to get the flu. Is there a bad strain going around? Did the flu vaccine target the right strain? Did you get
In the last few days, I have heard the term “data lake” bandied about in various client conversations. As with all buzz-term simplifications, the concept of a “data lake” seems appealing, particularly when it is implied to mean “a framework enabling general data accessibility for enterprise information assets.” And of
Last week I was chatting with some mathematicians and I mentioned the blog post that I wrote last year on the distribution of Pythagorean triples. In my previous article, I showed that there is an algorithm that uses matrix multiplication to generate every primitive Pythagorean triple by starting with the
I press a button, a miracle machine churns through all the calculations in the world and the answer to the Ultimate Question of Life, the Universe, and Everything[1] is produced as a single number. Oh hang on, that’s 42. Alright, for our microcosm, let’s stick to the answer to my

How simple is too simple, when it comes to analyzing data on a map? The KISS principle can be applied to many things, including graphs and maps. What is the KISS principle, you might ask? Well, it's not the rock band that my friend Patricia (pictured below) has been known
Tax fraud…5-7 years in prison. I thought I had it all figured out. The government wades through millions of returns and tries to issue refunds quickly. Sure, I filed over a thousand for my clients, but that’s just a blip on their radar. I never thought I’d get caught. But
Judging by the spike in media coverage of tax fraud, one might think accountants have suddenly been inspired by Breaking Bad re-runs, and turned en masse to lives of crime. Umm… no. But, there are two good reasons for all the attention. One reason is because of a new law
Today is my 600th blog post for The DO Loop. I have written about many topics that are related to statistical programming, math, statistics, simulation, numerical analysis, matrix computations, and more. The right sidebar of my blog contains a tag cloud that links to many topics. What topics do you,
I took another trip to California and, of course, allowed Ed to come with me. San Francisco is an amazing place to visit (especially in March when it’s cold and wet in North Carolina.) On this trip, we met with wonderful group of people, the California Transcribers and Educators for
Small to midsize businesses (SMBs) want to make the most of their data, but many feel they lack the skills and solutions to effectively harness it. However, new technologies and new channels to market are leading to the “democratisation of analytics” making it easily available to all. SMBs cannot
So, how did you first learn SAS programming? Originally, I was self-taught. Many years ago, I learned SAS on the job when a systems programmer quit and I took over supporting a mainframe performance software package that was written in SAS. I got a copy of the Base SAS users
In the 1988 film Beetlejuice, the title character, hilariously portrayed by Michael Keaton, is a bio exorcist (a ghost capable of scaring the living) hired by a recently deceased couple in an attempt to scare off the new owners of their house. Beetlejuice is summoned by saying his name three times. (Beetlejuice. Beetlejuice. Beetlejuice.) Nowadays

The Internet of Things (IoT) is going to take us into the next big technology wave, which will include a massive proliferation of personal connected devices like we have never seen before – cars, toothbrushes, household appliances, watches, medical devices, bicycles, and all sorts of things on our body and in
Whether it’s a smart water meter or a complex combustion turbine, expectations of reliability for complex, connected machines have increased across the board. Due to higher visibility and the availability of advanced analytics, companies know they should be able to identify emerging safety and reliability issues in these assets. By
As part of two of our client engagements, we have been tasked with providing guidance on an analytics environment platform strategy. More concretely, the goal is to assess the systems that currently compose the “data warehouse environment” and determine what the considerations are for determining the optimal platforms to support
I was recently asked by a customer if they should move the responsibility for creating the statistical baseline forecast. They were considering moving it from their regional country offices to their global headquarters.
