In some data mining applications, matrix norm has to be calculated, for instance [1]. You can find a detailed explanation of Matrix Norm on Wiki @ Here
Instead of user written routine in DATA STEP, we can obtain “Entrywise” norm via PROC FASTCLUS ef…

K-Nearest-Neighbor, aka KNN, is a widely used data mining tool and is often called memory-based/case-based/instance-based method as no model is fit. A good introduction to KNN can be find at [1], or @ Wiki.
Typically, KNN algorithm relies on a soph…
algorithms are proven to be very effective data mining tools, either used stand alone, or as a building block to handle nonlinearity, etc. Implementation of Boost algorithm in SAS is not easy to find although it is not difficult to wr…
In this post, I post an improved SAS macro of the single partition split algorithm in Chapter 2 of “Pharmaceutical Statistics Using SAS: A Practical Guide” by Alex Dmitrienko, Christy Chuang-Stein, Ralph B. D’Agostino.
