Did you know that there is a mathematical formula that simplifies finding the derivative of a determinant? You can compute the derivative of a determinant of an n x n matrix by using the sum of n other determinants. The n determinants are for matrices that are equal to the original matrix
The topic of sustainability has always been on the agenda at SAS in one way or another. As we become more educated and aware across the globe, and more regulatory factors come into play, expectations and accountabilities are under scrutiny like never before. I caught up with Malinda Salter, Senior

A newly proposed rule in the US aims to bring more transparency to those risks. In March, the US Securities
Many of us feel stressed at times. We may have a large to-do list, varied personal or professional tasks and so on. While short-term stress serves a purpose to get things done, a sense of overwhelm is a red flag that we are reaching our emotional capacity. As we recognize
SAS' Jordan Leiker shows you how any CAS action can be used with image data to create heat maps.
In The Essential Guide to Bootstrapping in SAS, I note that there are many SAS procedures that support bootstrap estimates without requiring the analyst to write a program. I have previously written about using bootstrap options in the TTEST procedure. This article discusses the NLIN procedure, which can fit nonlinear
Just getting started with this series? Make sure to explore Part 1 and Part 2. There are different ways you can use these two tools to accelerate model building, deployment and monitoring. Figure 1 summarizes best practices for conducting ModelOps using SAS Model Manager and Azure Machine Learning. Best practice
기업의 골든타임을 지켜준다는 것은 신속하게 인사이트를 확보한다는 것이며, 신속하다는 것은 바로 ‘접근 및 활용이 쉽다’라는 것을 의미합니다. 여러분의 업무와 일상생활에서 ‘골든타임’은 어떤 것이 있을까요? 우리가 잘 알고있는 골든타임으로, 심장쇼크가 왔을 때 심폐소생술을 수행하는 4분의 골든타임, 비행기가 비상착륙했을 때 승객을 대피시켜야하는 90초의 골든타임, 그리고, 회사의 이슈가 발생했을 때 위기대응을 시작해야하는 15분의

Our Employee Inclusion Groups (EIGs) are key to fostering a sense of belonging and acceptance. But what exactly do these groups do? Today, meet the Black Initiatives Group (BIG)
Recently, I wrote about Bartlett's test for sphericity. The purpose of this hypothesis test is to determine whether the variables in the data are uncorrelated. It works by testing whether the sample correlation matrix is close to the identity matrix. Often statistics textbooks or articles include a statement such as
The SGPLOT procedure supports a wide variety of plot types that you can use directly or combine together to create more complex graphs. Even with this flexibility, there might be times you run across a graph that you cannot create using one of the standard plot types. An "area" bar
