A reader asked whether it is possible to find a bootstrap sample that has some desirable properties. I am using the term "bootstrap sample" to refer to the result of randomly resampling with replacement from a data set. Specifically, he wanted to find a bootstrap sample that has a specific
Su negocio necesita tomar decisiones inteligentes a partir de datos confiables que generen resultados confiables.

When students hear the word data, they may envision measurements that scientists collect, or perhaps it has something to do with the social media platforms they love. Many students struggle to understand where data comes from and how it can help us make decisions and better understand our world! They may not make a connection with computer science either. Just as
Since 2015, the number of Americans who to listen to at least one podcast per month has increased by approximately 40 million people. The number of podcast listeners has also ballooned globally in tandem with a rise in smart speaker adoption. People are consuming them at home, on the go

This June the Work/Life Relationship Series sent emails for three weeks with relationship research, insights and tips. A weekly email also provided questions for conversations and closeness. I'm sure many of us may find ourselves occasionally staring silently at our partners, friends or family, as we continue to endure these
Graphing data is almost always more informative than displaying a table of summary statistics. In a recent article about "dynamite plots," I briefly mentioned that graphs such as box plots and strip plots are better at showing data than graphs that merely show the mean and standard deviation. This article
Tropical Storm Ana, which formed in May this year, officially made 2021 the seventh consecutive year that a storm formed before the season's designated start. Since then we have seen a number of storms, representative of an increase of severe weather over the past few years, especially as we remember
“Bias is not inhuman. To have bias is absolutely human,” says Banu Raghuraman. If data enthusiasts are going to break the cycle of bias, however, “we have to be more aware of where the data is coming from, what it’s trying to tell us and how we can break the
Word embeddings are the learned representations of words within a set of documents. Each word or term is represented as a real-valued vector within a vector space. Terms or words that reside closer to each other within that vector space are expected to share similar meanings. Thus, embeddings try to capture the meaning of each word or term through its relationships with the other words in the corpus.
Written by Valeria Ravani Since the pandemic began, travel has been restricted to help curb the spread of COVID-19. We’re all eager for the days when we can travel again – for work, or for pleasure! Until that time comes, we’re going to take you on a virtual world tour,
The field of probability and statistics is full of asymptotic results. The Law of Large Numbers and the Central Limit Theorem are two famous examples. An asymptotic result can be both a blessing and a curse. For example, consider a result that says that the distribution of some statistic converges
A recent report suggests that the current state of climate change is alarming. Climate change puts billions of people at risk of events like extreme hurricane seasons and rising sea levels. However, data and analytics play a critical role in informing us about the situation, planning ahead, and raising awareness
The SAS/IML language supports lists, which are containers that store other objects, such as matrices and other lists. A primary use of lists is to pack objects of various types into a single symbol that can be passed to and from modules. A useful feature of using lists is that
Earth’s natural capital deserves protection – for our sake and for the future. Analytics can help.
In this Q&A with MIT/SMR Connections, Iain Brown, SAS’s head of data science for the United Kingdom and Ireland, discusses technical readiness for AI, customer adoption trends, IT’s changing role, and mission-critical considerations for technology and talent. Q: What does it mean, from both a technology and a cultural standpoint,
I’m a Leo and love the sun and the sea! There is something magical about the ocean breeze, the sand between my toes and the glistening sun on the ocean waves as they easily flow in and out in a rhythmic, calm manner. I imagine the seaweed beneath the water’s
I previously wrote about one way to solve the partition problem in SAS. In the partition problem, you divide (or partition) a set of N items into two groups of size k and N-k such that the sum of the items' weights is the same in each group. For example,
As organizations increasingly use artificial intelligence to collect and analyze data and identify individuals, the topic of ethical AI often rears its head. Last year, Michigan's Integrated Data Automated System flagged more than 540,000 unemployment claims as possibly fraudulent. Thousands of state residents’ accounts were inaccurately flagged, making it almost
The partition problem has many variations, but recently I encountered it as an interactive puzzle on a computer. (Try a similar game yourself!) The player is presented with an old-fashioned pan-balance scale and a set of objects of different weights. The challenge is to divide (or partition) the objects into

A statistical programmer asked how to simulate event-trials data for groups. The subjects in each group have a different probability of experiencing the event. This article describes one way to simulate this scenario. The simulation is similar to simulating from a mixture distribution. This article also shows three different ways
The need for agile, accurate demand planning has never been greater. When considering migrating your demand management application to a cloud-native solution, you might experience platform management challenges ranging from lacking the resources needed to oversee application operations, to manipulating maintenance tasks that may distract from growing the business. Why
