Ya no se trata de imaginar cosas. Cada día las empresas enfrentan miles de desafíos. Desde decisiones de negocio hasta procesos operativos, pasando por la manera de relacionarse con sus clientes o de preparar los informes de cumplimientos regulatorios o cuidarse de los ataques o fraudes. No son escenarios que
El fraude y los delitos financieros cuestan a los gobiernos millones de dólares al año. Las agencias gubernamentales tienen que buscar más allá de los enfoques tradicionales para combatir estos crímenes cada vez más complejos y comunes. En este sentido y en beneficio de las entidades gubernamentales, la tecnología analítica
When I was in college, I lived in the Alexander dorm, where each room had an American student and an International student. I learned a lot about the rest of the world, and I also heard a lot of different languages being spoken. I'm really impressed when I hear people
È inutile negarlo, il digitale ha trasformato (e sta trasformando) il modo di fare impresa. I consumatori vogliono entrare in contatto con le aziende in ogni canale che hanno a disposizione (sito web, social, app, store fisico, call center, ecc…). E le aziende devono essere pronte a soddisfare e prevedere
There's been a lot of talk in the media lately about the death of retail. Every week, it seems like another retailer announces the closing of stores, acquisitions or even going out of business. Many relate it to the growing competitive landscape with the convenience of online shopping and lure
With busy week nights, some foods don’t make it to the table until the weekend simply due to lack of prep time. But, it’s a shame to narrow some of our favorite foods to only a few nights of the week. So, a quick solution when you’re in time crunch
In a previous article, I showed two ways to define a log-likelihood function in SAS. This article shows two ways to compute maximum likelihood estimates (MLEs) in SAS: the nonlinear optimization subroutines in SAS/IML and the NLMIXED procedure in SAS/STAT. To illustrate these methods, I will use the same data
In SAS Viya 3.2, the Self-Service Import provides a mechanism for a user to import (copy) data into the SAS Cloud Analytic Services (CAS) environment. The data is copied as a .sashdat file into the selected CAS Library location when it is imported. Self-Service Import data can only be imported into
지난 3월 31일 막을 올린 ‘2017 KBO 프로야구 정규시즌’이 어느새 중반부를 넘어섰습니다. 개막 두 달 만인 5월 30일 최소 경기 수 기준 역대 다섯 번째로 누적 관중 300만명을 넘어서며 식지 않는 인기를 과시하고 있는데요! 이처럼 수많은 관중들의 마음을 얻기 위해 그라운드 위 선수들의 치열한 경기 외에도 야구장 곳곳에서 다양한 시도들이
‘세계 야생 동물의 날(World Wildlife Day)’에 대해 들어보셨나요? 지난 2013년, 국제 자연 보호 연맹(IUCN) 산하 ‘멸종위기에 처한 야생동식물종의 국제거래에 관한 협약(CITES: Convention on International Trade in Endangered Species of Wild Flora and Fauna)’의 170여개 체약국은 3월 3일을 멸종 위기에 처한 야생 동물·식물에 대한 관심과 대책을 촉구하는 기념일로 지정했습니다. 이에 따라
Customizing the Kaplan-Meier plot in assorted ways is so popular that we devote an entire chapter to it in the SAS/STAT documentation.
Maximum likelihood estimation (MLE) is a powerful statistical technique that uses optimization techniques to fit parametric models. The technique finds the parameters that are "most likely" to have produced the observed data. SAS provides many tools for nonlinear optimization, so often the hardest part of maximum likelihood is writing down
Registration is now open for the SAS Analytics Experience 2017, being held September 18-20, in Washington, DC. (The Analytics Experience moves to Amsterdam, October 16-18 -- details on that event to follow.) For anyone interested in FVA analysis, Chip Wells and I will be delivering a half-day pre-conference training session
If you were a fan of the original Star Trek television series, you probably remember lots of little details about the show. And you might even feel sorry for the people who don't get the clever references you make to things from the show. If you're that person, then you'll
