I recently took a trip to Scotland, to attend the Highland Games! (ok - that statement might be a tiny bit misleading) It was a very cool and interesting event, and I wondered where and when other such events might be happening. What better way to analyze this kind of
The article "Fisher's transformation of the correlation coefficient" featured a Monte Carlo simulation that generated sample correlations from bivariate normal data. The simulation used three steps: Simulate B samples of size N from a bivariate normal distribution with correlation ρ. Use PROC CORR to compute the sample correlation matrix for
SAS 9.4 Maintenance 5 includes new support for reading and writing GZIP files directly. GZIP files, usually found with a .gz file extension, are a different format than ZIP files. Although both are forms of compressed files, a GZIP file is usually a compressed copy of a single file, whereas
My new SAS Press book “An Introduction to SAS Visual Analytics” (written in collaboration with Tricia Aanderud and Rob Collum) covers all of the different aspects of SAS® Visual Analytics, including how to develop reports, load data, and handle administration. Below is an example of the types of tips that you can find
Every day 91 Americans die from opioid abuse, every nine seconds a student drops out of high school and every 47 seconds a child is confirmed to be abused or neglected. These are sobering statistics that show the challenge our government leaders face to help those in need. While there
Uno de nuestros firmes pensamientos es que el activo más valioso de las empresas son sus datos y el buen uso de ellos es el que pueden llevar a las compañías a una real transformación digital del negocio. A pesar de esto la consultora Gartner comenta que los líderes aún tienen una
Correlations between variables are typically displayed in a matrix. Because the correlation matrix is determined by the order of the variables, it is difficult to find the largest and smallest correlations, which is why analysts sometimes use colors to visualize the correlation matrix. Another visualization option is the pairwise correlation
The latest post in our Equity in Education series focuses on the achievement gap. National achievement data show that our public education systems work well for students with means. And not so well for disadvantaged students. Racial achievement gaps are found in the National Assessment of Education Progress (NAEP), also
After a few tough years in the trenches, analytics leaders in utilities are emerging and making a difference as their utilities vie to stay relevant in the ever-changing energy landscape. At the core of this emergence are leaders that are embracing open analytics platforms and pushing analytics to the edge.
El precio que paga una empresa que se transforma digitalmente no sólo implica "asumir el costo cultural" de una visión disruptiva que modifica la operación del negocio. De hecho, es una suma real y que se refleja en las inversiones que realizan las organizaciones. Según datos de un estudio global , este año,
Sometimes life is just too busy, and I bet many of you feel the same way. If you’re like me, you’re playing a number of roles: employee, spouse, parent, community leader, coach and so on. With all the craziness, it’s likely we’re shortchanging another role that’s critically important to our
The movie Blade Runner came out about 30 years ago, portraying a dystopian future set in 2019 Los Angeles. Many of the technology predictions in the movie have actually become reality - but how about the weather and pollution? The movie was all about smog and a lack of sunshine, and I wondered
Editor-in-Chief Len Tashman's Preview of the Fall 2017 Issue of Foresight Artificial intelligence (AI) is the name commonly given to the ability of machines to mimic the human aptitude to reason, solve problems, and learn from experience. Research in this field over the past few decades has spanned many disciplines,
As traditional reserves deplete and oil prices rise, market analysts predict that the global demand for petroleum products will increasingly be met with oil extracted from non-traditional resources in more challenging and harsher environments. Therefore, companies across the oil & gas industry are evaluating technologies and processes that can deliver
If you perform a weighted statistical analysis, it can be useful to produce a statistical graph that also incorporates the weights. This article shows how to construct and interpret a weighted histogram in SAS. How to construct a weighted histogram Before constructing a weighted histogram, let's review the construction of
‘Quality‘ means many things to many people. It’s subjective and depends on the industry and product being made, but the fundamental objective is to provide the best product to the right standard associated to fit, form and function. And cost and required profit margin must also be taken into account.
"Coming to America" - it's been the name of a funny movie and a dramatic song (can you name the actor & singer without cheating?!?) It's also been a dream for many, and an action for some. People have been coming to America both legally and illegally for many years, but there's one special category
Los bancos colombianos han entendido que la transformación digital es una prioridad para su industria, sobre todo porque ya no solo están disputándose el mercado con los actores tradicionales sino que han empezado a cruzarse con las Fintech, las diferentes startups que han empezado a ofrecer nuevos servicios financieros basados en tecnología.
As smart city endeavors continue to ramp up globally, city planners and leaders are often curious to learn how cities around the world are planning to make their cities smarter with the Internet of Things. Recently, my colleagues and I met with a team from a major city in China
To do their jobs well, Joyce Norris-Montanari says users doing analytical data preparation need access to both standardized and raw data.
Las herramientas convencionales para el desarrollo de estrategias de marketing ya no son los suficientemente capaces de analizar en profundidad y al detalle todos los datos que son generados a diario por los consumidores. Es por esta razón que la analítica avanzada es una de las mejores aliadas para las empresas
How can you specify weights for a statistical analysis? Hmmm, that's a "weighty" question! Many people on discussion forums ask "What is a weight variable?" and "How do you choose a weight for each observation?" This article gives a brief overview of weight variables in statistics and includes examples of
For our third installment in this blog post series, let’s continue our journey to learn more from three SAS education customers. Today, we'll hear about the benefits their users and institutions have received by using SAS for data visualization and analytics. In this post, you'll hear from: Linda Sullivan, Assistant Vice President
I recently paddled in a boat race, and was wondering how I did compared to all the other paddlers. And being a Graph Guy, I decided I should find a cool way to graph the data ... Here's some background information ... There's a great organization called Bridge II Sports
분석이 매 순간, 데이터가 존재하는 모든 곳에 적용된다면 어떤 일들이 가능해질까요? 오늘날 우리는 데이터가 사회와 경제를 움직이는 ‘데이터 이코노미’ 시대에 살고 있습니다. IDC는 오는 2025년 전 세계 데이터 양이 현재의 10배에 달하는 163제타바이트(ZB)에 이를 것으로 전망했는데요. 그러나 데이터는 그 자체만으로 유용하지 않습니다. 모든 데이터는 대기 시간과 유효 기간의 속성을 지니기
One of the best parts of my job is hearing about all the cool ways people are using data for good. Increasingly, many of these stories are related to the Internet of Things, including: Smart pills that help patients stick to their treatment regimens. These ingestible sensors can monitor patients’
Depending on who you speak with you will get varying definitions and opinions regarding demand sensing and shaping from sensing short-range replenishment based on sales orders to manual blending of point-of-sales (POS) data and shipments. Most companies think that they are sensing demand when in fact they are
Orbitz recently published a map showing the most popular international travel destination for each of the 50 US states. It was an interesting map ... but of course, me being the Graph Guy, I had to pick it apart and create my own version. Follow along, and explore this interesting
In a large simulation study, it can be convenient to have a "control file" that contains the parameters for the study. My recent article about how to simulate multivariate normal clusters demonstrates a simple example of this technique. The simulation in that article uses an input data set that contains
Es una realidad. Según IDC el mercado mundial de Big Data Analytics está creciendo a un ritmo de 23,1 % cada año y llegará a casi 50 mil millones de dólares en el 2019. En la región latinoamericana la cultura analítica ya ha permeado de manera importante industrias como la
