KNN Classification and Regression in SAS
kNN stands for k Nearest Neighbor. In data mining and predictive modeling, it refers to a memory-based (or instance-based) algorithm for classification and regression problems. It is a widely used algorithm with many successfully applications in medi…
K-Nearest Neighbor in SAS
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…
