In previous posts, I discussed how to connect to the CAS server, how to execute CAS actions, and how to work with the results. Now it's time to learn how to filter CAS tables. First, I'll load the cars.csv file into memory from the sassfotware GitHub page. I'll start by using my CAS connection object conn, followed by the upload_file method from the SWAT package. The upload_file method loads a client-side file into memory on the CAS server and returns a reference ... Read More

In a similar way, you can compute the density function for the multivariate t distribution. This article discusses the density function for the multivariate t distribution, shows how to compute it, and visualizes the density for a bivariate distribution in two different ways. As for all multivariate computations, the computations are simpler when you express the formulas in terms of matrices and vectors. This article uses the SAS/IML language to evaluate the multivariate t distribution. ... Read More

This can leave us feeling unsure of what to say, who to say it to, and how to find support. I don’t keep it a secret that I am the parent of an LGBTQ young adult. This has been a rough week for me, full of uneasiness and fear of the future. I’ve spent time reflecting on how we can navigate these sometimes-overwhelming worries and still be productive workers, good parents, loving spouses and caring friends. I believe ... Read More

Feed: SAS Blogs. Author: Becky Graebe. There’s plenty of buzz about innovation and thinking outside of the box at SAS these days. But for those who attended SAS' Patent Dinner, the proof was in the patent. SAS Legal Counsel Director Tim Wilson offered opening remarks at The Umstead event. “So much of what we do in R&D fits into the development, the ‘D’ category,” he said. “What you have done by becoming patent inventors is on the ‘R’ side, not staying at the same level but bringing it up. That takes commitment, experience and often time away from loved ones.” ... Read More

Feed: SAS Blogs. Author: Rick Wicklin. Recently, I needed to solve an optimization problem in which the objective function included a term that involved the quantile function (inverse CDF) of the t distribution, which is shown to the right for DF=5 degrees of freedom. I casually remarked to my colleague that the optimizer would have to use finite-difference derivatives because "this objective function does not have an analytical derivative." But even as I said it, I had a nagging thought in my mind. Is that statement true? I quickly realized that I was wrong ... Read More

Companies vied for suitable treatments and in less than a year, COVID-19 vaccines were developed. This demonstrated clearly that the sector could move at speed when necessary. Though vaccines were supported by regulators, inefficiencies in vaccine and drug development were exposed. COVID-19 has changed how we live and work – quite possibly permanently. From hybrid workplaces to online shopping, the digital revolution is well and truly here. Furthermore, the transformation in life sciences and pharma has been extraordinary. However, the pandemic created a huge problem for ... Read More

In vielen Phänomenbereichen nehmen der Vernetzungsgrad der beteiligten Akteure und damit die Komplexität der Ermittlungen zu. Damit steigt die Menge an Daten, die während der Ermittlungen ausgewertet werden müssen. Abbildung 1: Analytik und künstliche Intelligenz (KI) in Sicherheitsbehörden Verfahrensübergreifende Recherchesysteme geben einen Überblick über Informationen, die in unterschiedlichen Datenquellen liegen. Daneben gibt es eine wachsende Zahl analytischer Anwendungen, die spezielle Fragestellungen in Phänomenbereichen wie organisierter Kriminalität, KiPo oder Extremismus behandeln. Ihnen ist gemein, dass sie mit Hilfe von Analytik und künstlicher Intelligenz relevante Informationen aus riesigen ... Read More

Feed: SAS Blogs. Author: Cristina Rodríguez. En mayo de 2022 en SAS hemos celebrado el mes de la salud mental y este año fue el primero en el que la compañía organizó el “Global Recharge Day”. El viernes 6 de mayo supuso un día libre para todos nosotros y las oficinas de SAS estuvieron cerradas en todo el mundo. El objetivo de esta jornada de descanso es poder tener unas horas de desconexión para recuperar energía y también para conectar con aquello que nos gusta hacer y reconforta. Después de meses trabajando en remoto, hemos vuelto a nuestras oficinas bajo ... Read More
