This post is a brief review of the book 'The Little SAS book' by Delwiche and Slaughter.
I came across this book in my first SAS position. It had been left behind by a former employee, or the company, and was sitting on the shelf of my cubical.
I had no experience with SAS, and all I had to refer to was the existing code in the system and this book.
As the title suggests it's quite a small book in IT terms, the fifth edition is 325 pages.
One benefit of this is…Continue

I have a 5-20K USD budget to get a tool (w/wo dedicated hardware), including training for 2 people, to prepare (clean, merge, etc...) and summarize (samples, grouping/aggregations, etc) large data sets (over 5GBs, over 4 million rows).
I need an efficient solution (fast data processing and fast to learn), and definitely easy to use. I would have done it with excel if excel could handle such large data files.
After preparing and summarizing the data, I'll use excel pivot tables…Continue
A very efficient approach to random sampling in SAS® achieves speed increases orders of magnitude faster than the relevant "built-in" SAS® procedures. For sampling with replacement as applied to bootstraps, seven algorithms are compared, and the fastest ("OPDY"), based on the new approach, achieves speed increases over 220x faster than Proc SurveySelect. OPDY also handles datasets many times larger than those on which two hashing algorithms crash. For sampling without replacement as applied…Continue
