For many univariate statistics (mean, median, standard deviation, etc.), the order of the data is unimportant. If you sort univariate data, the mean and standard deviation do not change. However, you cannot sort an individual variable (independently) if you want to preserve its relationship with other variables. This statement is
SAS Global Forumオンデマンド配信の紹介 SAS Global Forumは、年に一度開催される世界最大級のアナリティクス・カンファレンスです。南北アメリカ、アジア太平洋地域、EMEAの3つの地域ごとにイベントは分かれており、アジア太平洋地域は5/19（水）～5/20（木）に開催されました。イベントの内容は2021年6月25日（金）までこちらより、オンデマンドで視聴可能です。 Forumでは、様々な分野のトップ企業、スピーカーの刺激的な講演を聞くだけでなく、トレーニングや技術セッションといった学習機会も提供されます。また優れたデータアナリティクスの成績・教育が認められた学生や教育者に対しては表彰が行われました。ここでは一人の受賞者のセッションを紹介します。 Do Americans trust scientific experts? このセッションはタイトルにもあるように、医者・環境学者・栄養士など“科学に関連する専門家”に対するアメリカ人の不信について取り扱っています。この話題は幅広く活用が期待でき、多くの人々に関連する事柄であるという背景があり、今回の講演のテーマとして設定されています。 使用されたデータは、科学者に対する人々の全体的な意見や個人の科学にまつわる知識などを調査して収集されています。収集したデータを用いて、記述統計による考察やディシジョンツリーをはじめとしたモデルによる分類の結果から、次のようなフィードバックを共有しています。 各専門家に対する肯定的/否定的な意見の割合は、医者が最も肯定的な割合が高く、その中でも人々と対面する機会が多い開業医に対する肯定的な意見が多い。 人々の政治的傾向に基づいて専門家への信頼度に差が出ている 科学知識が前提にある人の方が専門家への信頼を示している スピーカーはこの結果をもとに、ワクチン接種の促進が可能になるのではないかという活用例を話しています。それは市民に専門への信頼に関する質問に答えてもらい、信頼の低い地域の人々に対してワクチン情報について教育・説得することでワクチン接種を増やすという仕組みです。 またスピーカーは私たちと同じ大学の学生で、コロナ禍に抱える問題も絡ませたセッションになっており、私たちにとても身近な内容になっています。 繰り返しになりますが、SAS Global Forum2021はより優れたキャリアにつなげる大きなチャンスであり、各セッションの様子はオンデマンドで視聴可能です。ぜひ自らの成長のために登録、ご覧ください。
Our traditional assumptions about data are evolving, and so is our understanding of data literacy. Data is more than numbers, charts and graphs. And data literacy is not just for data scientists. “If you’re talking with people who aren’t already data fluent, you have to make them aware that data is

Recently, we’ve released a new feature in ASTORE: score with multiple analytic stores. In the process, we may create multiple analytic stores with dependencies among them (the output of some analytic stores is an input to others). This feature streamlines the scoring process of multiple analytic stores. It enables the
We’ve all experienced the value that innovation has brought to our lives. The cloud, enormous data sets and more accurate AI modeling have enabled many organizations to bring new products and services to market in ways we could not have imagined 20 years ago. The health care and life sciences
You've probably seen a population pyramid, such as this one I showed in a previous blog post. But let's scrutinize population pyramids a bit deeper, with an eye on special features that can make them even more useful! I was inspired to give population trees a second look by this
While live advisors sleep, this friendly, sophisticated chatbot is there to help victims of identity fraud.
It is well known that classical estimates of location and scale (for example, the mean and standard deviation) are influenced by outliers. In the 1960s, '70s, and '80s, researchers such as Tukey, Huber, Hampel, and Rousseeuw advocated analyzing data by using robust statistical estimates such as the median and the
Minnesota's longitudinal data system integrates early childhood education, K-12, postsecondary and workforce data to create a panoramic view of education outcomes. The merging of systems results in data linking and improves the overall data quality and performance of the P-20 Statewide Longitudinal Education Data System (SLEDS) and Early Childhood Longitudinal
분석은 왜, 전사적으로 활용되지 못할까요? 최근 맥킨지 연구에 따르면 AI와 분석을 전 세계 산업 전반에 적용할 경우, 약 9조~15조 달러의 가치 창출이 가능합니다. 그런데도 오직 8%의 주요 기업만이 전사적으로 분석을 활용하고 있습니다. 무려 90% 이상의 기업이 분석을 조직의 모든 영역으로 확산하지 못하고 있는 것입니다. 조직 내 분석 확산과 관련하여 주요 관계자들은 각기 다른 고민을 안고 있습니다. ▶IT리더는 제한된 비용으로 신기술을 적용하고 혁신을 이루어야 합니다. 한편으로는 끊임없이 개발 및 변경되는 분석 모델을

Mental health and data sharing. Seeing those phrases in a single sentence gives even the most seasoned professionals pause. This is legitimately sensitive data. And there are often specialized confidentiality and privacy laws due to the stigma and discrimination against those with mental health disorders. All the same, many agencies are starting to ask
When data contain outliers, medians estimate the center of the data better than means do. In general, robust estimates of location and sale are preferred over classical moment-based estimates when the data contain outliers or are from a heavy-tailed distribution. Thus, instead of using the mean and standard deviation of
Most computers can execute operations in parallel due to their multicore infrastructure. Performing more than one operation simultaneously has the potential to speed up most tasks and has many practical uses within the field of data science. SAS Viya offers several products that facilitate parallel task execution. Many of these
In the US we are seeing rapid changes related to COVID-19 cases, the ending of mask requirements and messages of “a return to normal”. I want to be sensitive to the fact that not all parts of the US or the world are seeing improvements and in some places the
In her Ted Talk, Gavriella Schuster, Corporate Vice President of Commerical Partner Team at Microsoft, shares that in 1991, 36% of the computing workforce in the United States was women. In 2020, that number fell to 25%. We're going in the wrong direction of gender equity in high tech.
