You've seen the terms #squadgoals or #lifegoals - to me, one #worklifebalancegoal is to be able to have time to volunteer outside of work. I could go on about the importance of service and how we are all connected but will have to save that soapbox for a different blog/time. From a happiness
Jupyter Notebookとは？ Jupyter Notebookとは、ノートブック形式のインターフェースでコードの開発（記述や実行）ができるWebアプリケーションです。約50ほどの世の中のプログラミング言語に対応しています。 http://jupyter.org/ Jupyter and SASとは？ Jupyterの環境に、オープンソースのSAS kernel for Jupyterを追加することで、Jupyter Notebook上でSAS言語を使用（シンタックスのハイライト、実行、ログの確認、アウトプットの表示）することが可能になります。 Jupyter Notebookでは、作業の内容は、ノートブック（*.ipynb）形式で保存されます。Jupyter Notebookでは、SASコードや実行結果だけでなく、リッチテキスト形式で文章を記載することが可能です。ノートブックはHTML形式や、PDF、あるいはSASコードとして出力することも可能です。 SAS 9.4とLinux環境があれば、ほとんどの方が導入・ご利用いただくことが可能です。 Jupyter Notebookを開くと、Notebookダッシュボードが表示されます。ここに、ノートブックや他のファイルの一覧が表示されます。 SAS University Editionでも使えますか？ 2016の7月から、Jupyter NotebookとSAS Kernel for JupyterがSAS University EditionのvAppに含まれることになりました。従来、SAS University Editionのインターフェースは、SAS Studioのみでしたが、今後はJupyter Notebookもご利用いただくことが可能となります。 https://support.sas.com/software/products/university-edition/faq/jn_whatis.htm
In my last post, I talked about how to observe the impact of modernisation through a data quality lens. I asked you to consider the quality of your legacy data and what that means on the "shiny new toy" you intend to buy in the future. In this post, I
One of my favorite quotes is: "You can't believe everything you read on the Internet" - Abe Lincoln, 1868. And that is especially true when it comes to graphs and statistics. Hardly a day goes by without me seeing a bad graph that misrepresents the data (either intentionally or unintentionally) .
There was a recent comment on the original 'Unbox Your Box Plots', where a user wants to see the original data for the box, but only label the outliers. As noted in the comment, labeling all the scatter markers and turning on the outlier display is not ideal. But there

Open Source und SAS – das sind auf den ersten Blick zwei ganz verschiedene Welten. Dabei verfolgt SAS eine ganze Reihe von Initiativen rund um Open Source – insbesondere im Umfeld des Big-Data-Frameworks Hadoop. Ich habe Andreas Gödde zum Nebeneinander und Miteinander der Technologien befragt. Andreas Gödde berät viele Kunden
Last week I read an interesting paper by Bob Rodriguez: "Statistical Model Building for Large, Complex Data: Five New Directions in SAS/STAT Software." In it, Rodriguez summarizes five modern techniques for building predictive models and highlights recent SAS/STAT procedures that implement those techniques. The paper discusses the following high-performance (HP)
This weekend I was reviewing my portfolio of stocks as usual. Yes, I do have a small stock portfolio with a few stocks, and normally I use free stock charting software to review the stock plots. These sites allow you to view the daily stock prices along with many technical
Slack is a tremendously popular app for team collaboration. At its core, it's an open messaging app that allows team members to communicate with each other in real time. It works well with "startup"-style teamwork, which requires constant communication among people who aren't always located together. I've heard a lot
The Internet of Things (or IoT, as some like to call it) holds a number of benefits for many organizations: revenue growth, smarter decision making and efficiency. Experts are predicting anywhere from 20 to 50 billion devices will be connected to the internet by 2020. That’s almost here! Are you
