Feed: SAS Blogs. Author: Conor Hogan. Just getting started with this series? Make sure to explore the earlier posts Part 1, Part 2 and Part 3. Up until now, you have seen how ModelOps can solve your biggest machine learning challenges and that SAS and Microsoft, together, can help you deploy, govern and monitor your models anywhere in the Microsoft Cloud. But what does that look like in practice and what value does that provide you? In this blog, we will share how to register SAS and open-source models from SAS Model Manager to Azure Machine Learning and then call ... Read More

Feed: SAS Blogs. Author: Sundaresh Sankaran. By Sundaresh Sankaran & Ali Aiello, Global Technology Practice, SAS Institute Many analytics developers prefer Python for its ease of use, versatility and community support. Acknowledging this from an early stage of Viya’s evolution, SAS has progressively provided access to Python from within its applications, the latest being SAS Studio. The Proc Python procedure, Python code editor & Python code step facilitate low-code analytics calling Python and SAS from a common interface. Data scientists also appreciate the connection to Python & R through the Model Studio Open-source Code node. Older methods of interaction include the swat and ... Read More

Feed: SAS Blogs. Author: Rick Wicklin. In categorical data analysis, it is common to analyze tables of counts. For example, a researcher might gather data for 18 boys and 12 girls who apply for a summer enrichment program. The researcher might be interested in whether the proportion of boys that are admitted is different from the proportion of girls. For this analysis, the data that you type into statistical software (such as SAS) does not typically consist of 20 observations. Rather, the data often consists of four observations and a frequency variable (also call a count variable). The first two ... Read More

But who is the "customer" in the telecommunications industry? Is it a "sim" that uses our service? Or is it the identification number to which that sim is assigned? Or maybe we should look for an even higher level in this hierarchy? Household in focus I will risk saying that the "entity" whose well-being operators should take care of should be the decision-making center on which the purchases, changes, ... Read More

Feed: SAS Blogs. Author: Jagruti Kanjia. Authors: Ricky Tharrington and Jagruti Kanjia In this post, you’ll learn how to assess the bias of machine learning models using tools available in SAS Viya 4. As artificial intelligence grows in popularity, the lives of individuals are increasingly impacted by the predictions of machine learning models in ways ranging from ad suggestions on social media to credit application approvals. Regardless of the importance of the scenario, every model application has the potential to affect separate segments of the user population differently. It’s important for data scientists to understand the biases present in their ... Read More

Feed: SAS Blogs. Author: Carlos Pinheiro. The Vehicle Routing Problem (VRP) algorithm aims to find optimal routes for one or multiple vehicles visiting a set of locations and delivering a specific amount of goods demanded by these locations. Problems related to the distribution of goods, normally between warehouses and customers or stores, are generally considered vehicle routing problems. The VRP was first proposed by Dantzig and Ramser in the paper "The Truck Dispatching Problem," published in 1959 by INFORMS in volume 6 of the Management Science journal. This paper searches for an optimal route for a fleet of gasoline delivery ... Read More

Curious as to what all the hypes about? Let’s dive in! What is Fascia? Fascia is an interconnected form of connective tissue in the body (tendons, ligaments, cartilage, and bone are some others). There are two main fascial layers. Try to envision the first one, the superficial layer, as a full body “saran wrap” compression suit that sits just beneath the skin. This superficial fascia covers you from head to toe ... Read More

Feed: SAS Blogs. Author: Cornelia Reitinger. Broadband has become widely available and 5G is up and running in many countries, meaning more and more people have access to the internet via different platforms. With good quality internet connections either at home or via mobile connections, consumer behaviour has changed rapidly. Those who have been in digital advertising for a while will remember the early to mid-2010s when every year was supposed to be the "year of mobile." The next big money-spinner everyone was really excited about was video advertising. Viewing time has increased rapidly over the last few years and ... Read More

Feed: SAS Blogs. Author: Dan Heath. Amazing things can be created when you start with small pieces and stack them together. Just ask Bryan Berg. He is the current world record holder for the tallest house of cards. This same principle can be applied to the SGPLOT and SGPANEL procedures. You can take the individual plot types and stack them in a way that creates some very interesting and effective graphics. Consider the graph below. The SERIES plot is showing S&P 500 P/E ratios from 1981-2009. Whenever the ratio exceeds 20, the area under the iine is highlighted in red ... Read More

Feed: SAS Blogs. Author: Jason Burke. In my last interview, I spoke with Malinda Salter about global trends, innovation and regulatory factors influencing businesses in the market now and in the coming years. In today’s interview, we focus in on how strategic considerations are converging with customer expectations and awareness, and how environmental, social and governance standards are driving active changes in products and service considerations for the C level. I spoke with Patrick Dittli from SAS, who is no stranger to these topics. His senior positions in retail and consumer goods businesses provide compelling and realistic perspectives. Strategic shifts ... Read More
