This blog post demonstrates process and SAS coding techniques to shift dates by a given number of workdays accounting for weekends and holidays.
2020 is here and systems that use 2-digit years in date values are getting confused. Do we mean 1920 or 2020? In SAS, the YEARCUTOFF= option lets you decide.
Parts 1 and 2 of this blog post discussed exploring and preparing your data using SASPy. To recap, Part 1 discussed how to explore data using the SASPy interface with Python. Part 2 continued with an explanation of how to prepare your data to use it with a machine-learning model.
The t-test is a very useful test that compares one variable (perhaps blood pressure) between two groups. T-tests are called t-tests because the test results are all based on t-values. T-values are an example of what statisticians call test statistics. A test statistic is a standardized value that is calculated

Just when you think you’ve seen it all, life can surprise you in a big way, making you wonder what else you've missed. That is what happened when I recently had a chance to work with the SAS® Scalable Performance Data Server, a product that's been around a while, but
This article is not a tutorial on Hadoop, Spark, or big data. At the same time, no prerequisite knowledge of these technologies is required for understanding. We’ll give you enough background prior to diving into the details. In simplest terms, the Hadoop framework maintains the data and Spark controls and
Have you ever tried to pass comma-delimited values to SAS macro or to a SAS macro function? How can SAS distinguish commas separating parameters or arguments from commas separating parts of the values? Passing comma-delimited value as an argument to a SAS macro function Let’s say you want to extract
I was sitting in a model railroad club meeting when one of our more enthusiastic young members said, "Wouldn't it be cool if we could make a computer simulation, with trains going between stations and all. We could have cars and engines assigned to each train and timetables and…" So,
