Working with recurrence relations in SAS
Many textbooks and research papers present formulas that involve recurrence relations. Familiar examples include: The factorial function: Set Fact(0)=1 and define Fact(n) = n*Fact(n-1) for n > 0. The Fibonacci numbers: Set Fib(0)=1 and Fib(1)=1 and define Fib(n) = Fib(n-1) + Fib(n-2) for n > 1. The binomial coefficients (combinations
See how data can be used to improve the world
Five years ago, 193 countries joined forces and formed the United Nation’s Sustainable Development Goals. These goals, which are commonly referred to as the Global Goals, serve as a universal promise—an ambitious pledge to build a better future for people and planet by 2030. This year marks the final 10-year

The value of a low-code/no-code approach to building machine learning models
Everyone knows that SAS has been helping programmers and coders build complex machine learning models and solve complex business problems for many years, but did you know that you can also now build machines learning models without a single line of code using SAS Viya? SAS has been helping programmers
Analytical competence needed to drive innovation in Poland
Innovation is currently an extremely desirable feature for every country. However, a ranking published by the European Commission shows that Poland is struggling to create an environment that supports development. Development and innovation need people with competence in new technologies, such as analytics. Last year’s Modelling for Business conference showed
Innovation accelerators need strong analytics architecture to drive scale
What analytics architecture is needed to support an accelerator? I have recently been working with my colleague Jussi Martikka to extract lessons from the City of Helsinki’s AI Experimentation Accelerator work. We used the steps of the accelerator process to define the analytics architecture needed. This was a useful way
Regression with inequality constraints on parameters
A previous article discussed how to solve regression problems in which the parameters are constrained to be a specified constant (such as B1 = 1) or are restricted to obey a linear equation such as B4 = –2*B2. In SAS, you can use the RESTRICT statement in PROC REG to
Usage of forecasting in organizations
The practice of business forecasting falls well short of the potential exhibited in academic research and forecasting competitions. Chris Chatfield* noted this in a 1986 editorial in the International Journal of Forecasting, where he called on statisticians to find a better way of communicating the better use of existing methods
Mental health and criminal justice connections studied in innovative California program
Getting people with mental health conditions the help they need is a top priority for many Californians, according to a recent California Health Care Foundation report. In 2004, Golden State voters approved the Mental Health Services Act (MHSA). Enacted into law in January 2005, MHSA has generated approximately $15 billion
How to unquote SAS character variable values

Transforming Actuarial Work With Better Risk Modelling and Dynamic Pricing
Whenever I talk to actuaries across EMEA, they are very consistent in the many anchor points they see for actuarial modernization in order to be future-proof. In this article, I would like to share some of them. Anchor points for actuarial innovation The most time-consuming task is, of course, getting
Using SAS® to analyze and visualize a quadratic ANCOVA model
Learn how to use the SGPLOT procedure for graphical representation when you perform statistical analysis for a quadratic ANCOVA model with the GLM procedure.
The future of retail with SAS Analytics on Azure
I recently sat down with Colin Wright, Global Solutions Director of Retail & Consumer Goods at Microsoft, to explore the opportunities that SAS and Microsoft’s new strategic partnership creates for retailers around the world. Retailers are awakening to the fact that the near limitless scale and compute power of the
Restricted least squares regression in SAS
A data analyst recently asked a question about restricted least square regression in SAS. Recall that a restricted regression puts linear constraints on the coefficients in the model. Examples include forcing a coefficient to be 1 or forcing two coefficients to equal each other. Each of these problems can be
Which skills will dominate in the intelligent decisioning era?
The popular image of data scientists is very much a bit of a geek or nerd. However, that’s not strictly accurate. It may not be – as Harvard Business Review famously suggested – the sexiest job of the 21st century. But it is a long way from the perceived world
Using REST API to transform a Visual Analytics Report
There are three types of visualization APIs defined in the SAS Viya REST API reference documetation: Reports, Report Images and Report Transforms. You may have seen the posts on how to use Reports and Report Images. In this post, I'm going to show you how to use the Report Transforms
Permission to Widen the View
Right now people are living with a great amount of grief and uncertainty. We can’t dismiss our feelings or our very justified worries and concerns. However, we can have a both/and way of thinking. It may help to think of it this way: When we are anxious or uncertain, our
Bringing peace of mind to COVID-19 modeling with prediction and causation
A note from Udo Sglavo: In Digital transformation, scientific computing, and peace of mind, I mention that the COVID-19 pandemic is paralyzing the world. However, new challenges are also inspiring new ideas to tackle those challenges. We might ask questions about what is causal in nature, trying to figure out
Building custom apps on top of SAS Viya, Part Three: Choosing an OAuth flow
This is the third installment of a series focused on discussing the secure integration of custom applications into your SAS Viya platform. I began the series with an example of how a recent customer achieved value-add on top of their existing investments by building a custom app for their employees
Workforce Scheduling at an Animal Shelter
[Nabaruna Karmakar was coauthor of this post] A study was conducted at the University of Denver on The Economic Impacts of the Austin, Texas "No Kill" Resolution. The study found great value in creating an animal welfare-focused community. It highlighted the benefits of economic growth due to an increased need in
Video: How to Write a Custom Parallel Program in SAS Viya
My 2020 SAS Global Forum paper was about how to write custom parallel programs by using the iml action in SAS Viya 3.5. My conference presentation was canceled because of the coronavirus pandemic, but I recently recorded a 15-minute video that summarizes the main ideas in the paper. One of

Iterative proportional fitting in SAS
I previously wrote about the RAS algorithm, which is a simple algorithm that performs matrix balancing. Matrix balancing refers to adjusting the cells of a frequency table to match known values of the row and column sums. Ideally, the balanced matrix will reflect the structural relationships in the original matrix.
The hybrid approach to enhancing your natural language processing
Unlocking the potential of your unstructured text data can lead to great business outcomes but the prospect of starting a new or enhancing your existing Natural Language Processing (NLP) program can feel overwhelming because of the inherently unique (and sometimes messy) nature of human language. Text data doesn’t fit neatly into rows or columns the way that structured data does, which can make it seem more complex to work with. Conversations and written language range from objective statements to subjective perspectives and opinions. The same sentence, depending on its intent and the nuances in how it's said, can have a positive, negative, or neutral sentiment. To get us started, we'll share different types of NLP models used to analyze unstructured data with a focus on the hybrid approach.
