For those of us who haven’t been hermits stuck in a remote section of Middle Earth, The Lord of the Rings book and movie series brought to our awareness the mythical powers of The One Ring: An object with a sinister inscription that reads “One Ring to Rule Them All.”
Optimization for machine learning is essential to ensure that data mining models can learn from training data in order to generalize to future test data. Data mining models can have millions of parameters that depend on the training data and, in general, have no analytic definition. In such cases, effective models
El papel del CEO en las grandes empresas ha venido transformándose a la velocidad con que la tecnología dispone para él la información crítica de su negocio. Y ahora que puede tenerla casi al instante, su protagonismo y responsabilidad son mayores. Para gerentes de vanguardia. >> Vea también: Analítica y
What's more, CXOs who believe that they can substitute data scientists for real data integration are as foolish as the duffer who consistently uses the wrong club.
It’s hard to pick up a medical journal or news article these days without reading something about the gut microbiome. Thanks to the NIH Human Microbiome Project established in 2008, health professionals and the general public have learned much about the link between the condition of our gut microbiome and
Graphs enable you to visualize how the predicted values for a regression model depend on the model effects. You can gain an intuitive understanding of a model by using the EFFECTPLOT statement in SAS to create graphs like the one shown at the top of this article. Many SAS regression
El creciente uso de Internet en México y América Latina, ha significado un reto para las empresas de todos los tamaños e industrias, pues se han abierto oportunidades de negocio que les permiten contar con una mayor cobertura y presencia, sin embargo, aunado a ello han llegado los retos de
Report designers often discover after aggregating data by groups in the Visual Analytics Designer that it would also be nice to see additional aggregations of the data, for example, a maximum or minimum of that sum across groups. This means creating an ‘aggregation of an aggregation.’ If you plan your report objectives in
In recent years, more and more people have been registering as independent voters in the US, rather than Democrat or Republican - the independents now control well over 1/3 of the votes. Will they likely vote for the Democrat or Republican candidates in the upcoming election? Let's break down some numbers
As we are all well aware, providing caregiving for our parent(s) is complicated and messy. Siblings can often be both a blessing and a curse in this process, providing much needed relief and support, or perhaps creating additional stress and barriers to important decisions and resources. Why is this the
At the most recent SAS Global Forum in Las Vegas, I gave a demo on using SAS/OR to compute an optimal strategy for the casino game blackjack. For anyone who wasn't able to attend, I'd like to show some of the code and results here.
Fellow Roundtable writer David Loshin has commented in the past that: "MDM is popular because it is presented as a cure-all solution to all data problems in the organization." Many people see master data management (MDM) as the silver bullet to all of their business and data woes. But in
Some estimates suggest that the number of connected objects will be more than 50 billion by 2020. Each of us will own between six and 10 connected objects. But what exactly is the Internet of Things (IoT)? Wikipedia describes it as “the network of physical objects — devices, vehicles, buildings
Every beginning SAS programmer learns the simple IF-THEN/ELSE statement for conditional processing in the SAS DATA step. The basic If-THEN statement handles two cases: if a condition is true, the program does one thing, otherwise the program does something else. Of course, you can handle more cases by using multiple
A Turnip Graph displays the distribution of an analysis variable. The graph displays markers with the same (or close) y coordinate by displaying the markers spread out over the x-axis range in a symmetric pattern. Recently, a question was posted on the SAS Communities page regarding such a graph. Here is an example of
