Solve the Missionaries and Cannibals Problem with SAS
The Missionaries and Cannibals Problem (MCP) is a classic river-crossing logic puzzle. With SAS, we can solve this problem, visualize the solutions with SAS NETDRAW procedure and generate steps for any MCP problems.
Where are the files that you have access to through SAS® Studio?
SAS' Bari Lawhorn shows you how to access files you've stored with SAS® Studio.
Jedi SAS tricks: resizing, renaming and reformatting your data
SAS' Mark Jordan shows you how to modify data using PROC SQL, PROC DATASETS and SAS macros.
You can’t teach an old dog new tricks… or can you?
When we moved out to the country with our two dogs, our oldest dog Todd suddenly decided he liked to howl…. And he would do so every time we left the house. Maybe it was the country air? Maybe it was a time-lapse gene? Maybe he just wanted to learn
Solve "A Puzzle for Pirates" with SAS
This article introduces how to solve the pirate game with a recursive solving algorithm in SAS, and how to analyze and visualize the law behind the complex logic of the pirate game. If you join in a pirate game next time, you can know your destiny ahead of time to reap the benefits and avoid getting killed.
How to use the SAS Auto Call facility
Many SAS programmers use macros. I have seen students in my SAS classes use several methods to activate their macros. One way is to load the macro in the Display manager or editor in SAS OnDemand for Academics and submit it. Another technique is to use the statement %Include macro-name.
Jedi SAS Tricks: GIT my macros
I use macros extensively in my SAS programs, and over the years have accumulated a few that I find quite useful. The integration of GIT and SAS Studio has made it easy to build a re-usable macro library, so I've put some of the more polished macros I've written in
Calculating the overlap of date/time intervals
Leonid Batkhan describes and discusses pros and cons of 3 different algorithms and SAS code implementations to calculate length of overlap of date/time intervals and integer intervals in general.
Two macros for detecting data errors
Last year, I wrote a blog demonstrating how to use the %Auto_Outliers macro to automatically identify possible data errors. This blog demonstrates a different approach—one that is useful for variables for which you can identify reasonable ranges of values for each variable. For example, you would not expect resting heart
