SAS/STAT software contains a number of so-called HP procedures for training and evaluating predictive models. ("HP" stands for "high performance.") A popular HP procedure is HPLOGISTIC, which enables you to fit logistic models on Big Data. A goal of the HP procedures is to fit models quickly. Inferential statistics such
In this post I wanted to bring attention to the book Adult Children of Emotionally Immature Parents: How to Heal from Distant, Rejecting, or Self-Involved Parents. Of the 2,000+ books that are in our Work/Life Library, this is a book that I refer to most often. I continue to receive
In short, digital transformation concerns competition, speed, quality and costs. In the current connected world, the consumer has a lot of choices and is also less bound to a single provider. The customer expects immediate answers to rely on. Will someone wait two weeks for a loan approval, or will
When fitting a least squares regression model to data, it is often useful to create diagnostic plots of the residuals versus the explanatory variables. If the model fits the data well, the plots of the residuals should not display any patterns. Systematic patterns can indicate that you need to include
My last blog post discussed the applications of AI in retail and how retailers were starting to use solutions like image recognition to improve customer experience. However, implementing AI is not without its challenges. This post continues the conversation with Shailesh Jain, Group Head of Analytics at Landmark Group, about
As the sharing economy grows, you can catch a ride on Uber, have meals delivered by Grubhub ... and even stay in someone else's house (rather than a hotel) via sites like Airbnb. And speaking of that last one, I recently read an article listing Airbnb's top 20 'wish-listed' homes
Foi em Dezembro de 1991 que a relação do SAS e a Fidelidade começou, na altura entre o representante do SAS em Portugal e a Bonança, mais tarde integrada no que é hoje a Fidelidade, sendo que em 1995 e já com o SAS Portugal, foram assinados dois licenciamentos, um
A previous article describes the DFBETAS statistics for detecting influential observations, where "influential" means that if you delete the observation and refit the model, the estimates for the regression coefficients change substantially. Of course, there are other statistics that you could use to measure influence. Two popular ones are the
David Loshin suggests that reference data could be the foundation of future governance structures.
My article about deletion diagnostics investigated how influential an observation is to a least squares regression model. In other words, if you delete the i_th observation and refit the model, what happens to the statistics for the model? SAS regression procedures provide many tables and graphs that enable you to
In these modern times, my utility bill has a bar chart so I can see how my current consumption compares to my historical usage. I decided to create my own version of this utility bill bar chart, and make a few improvements along the way. If you're into SGplot bar
In this 'Rosetta Graph' example, I demonstrate how to control bar chart colors in Gchart and SGplot. But first, here's a little diversion... some artwork in my office here at SAS. There's a *lot* of artwork hanging around at SAS, but this particular painting wasn't created by the SAS artists
For linear regression models, there is a class of statistics that I call deletion diagnostics or leave-one-out statistics. These observation-wise statistics address the question, "If I delete the i_th observation and refit the model, what happens to the statistics for the model?" For example: The PRESS statistic is similar to
June is PRIDE month and there are lots of cool events at SAS and in the community that you can attend to celebrate and learn and have fun. In this blog I am going to share some tips on being an ally-- not just in June, but all year round.
Os novos paradigmas resultantes da introdução de novas tecnologias e da alteração de comportamentos e hábitos de consumo, resultam em forças esmagadoras que pressionam as indústrias a alterações substanciais na forma como trabalham e interagem com os seus clientes. A área dos Seguros não é exceção e movimentos de consolidação

Banks see open source as a hotbed of innovation – and a governance nightmare. Do the rewards outweigh the risks? Open source software used to be treated almost as a joke in the financial services sector. If you wanted to build a new system, you bought tried and tested, enterprise-grade
Recoding variables can be tedious, but it is often a necessary part of data analysis. Almost every SAS programmer has written a DATA step that uses IF-THEN/ELSE logic or the SELECT-WHEN statements to recode variables. Although creating a new variable is effective, it is also inefficient because you have to
How intelligent decisioning solutions can help you stay relevant in the era of digital banking Fierce competition, advances in technology, and consumer expectations for hyperpersonalised services are forcing the financial services sector to evolve. To adapt to rapid market developments, many banks and insurers are launching ambitious digital transformation projects.
Soccer (or football) fans everywhere will turn their eyes to France over the next month to cheer on amazing women from 24 countries contending on the global stage. These women compete at the highest level in an area that for too long was viewed as a man’s game. In many
For my third 'Rosetta Graph' example, I will focus on a simple pie chart. Hopefully this example will show you how to convert your SAS/Graph Proc Gchart pies into almost-identical Proc SGpie pies. And speaking of almost-identical pies, here are two beautiful pies my friend Beth made - which one
A family of curves is generated by an equation that has one or more parameters. To visualize the family, you might want to display a graph that overlays four of five curves that have different parameter values, as shown to the right. The graph shows members of a family of
You've probably heard of the famous Rosetta Stone. It had the same decree written on it in both ancient Egyptian and Greek, and was an essential key to help modern historians decipher and translate the ancient Egyptian hieroglyphs. To help the 'old timers' (like me) shift from using SAS/Graph to the
The hype around artificial intelligence has never been higher – and retail is one industry where it has a chance to make a major impact on profits. But as hype and misunderstandings continue to build, it's become harder than ever to keep sight of the true disruptive potential of AI. I
Statistical programmers and analysts often use two kinds of rectangular data sets, popularly known as wide data and long data. Some analytical procedures require that the data be in wide form; others require long form. (The "long format" is sometimes called "narrow" or "tall" data.) Fortunately, the statistical graphics procedures
Knowing how to visualize a regression model is a valuable skill. A good visualization can help you to interpret a model and understand how its predictions depend on explanatory factors in the model. Visualization is especially important in understanding interactions between factors. Recently I read about work by Jacob A.

St. Louis is home to Anheuser Busch, the legendary Cardinals baseball team, and Ameren, where analytics rocks. More on this later.

Business Intelligence (BI) begleitet uns schon seit geraumer Zeit – und zwar in ganz unterschiedlichen Ausprägungen. Und das Thema wird immer wichtiger und verändert sich im gleichen Maße, wie Unternehmen den Wert datengetriebener Entscheidungen erkennen. Damals und heute BI war in „jungen Jahren“ geprägt von teuren, komplexen Systemen, die sich

It can be hard to get a handle on what artificial intelligence (AI) and machine learning (ML) will actually do. We all understand – in theory, at least – that they could change the way we live and work. In most cases and for most of us, however, the precise
