The DO Loop
Statistical programming in SAS with an emphasis on SAS/IML programs
Do you want to bin a numeric variable into a small number of discrete groups? This article compiles a dozen resources and examples related to binning a continuous variable. The examples show both equal-width binning and quantile binning. In addition to standard one-dimensional techniques, this article also discusses various techniques
Binning transforms a continuous numerical variable into a discrete variable with a small number of values. When you bin univariate data, you define cut point that define discrete groups. I've previously shown how to use PROC FORMAT in SAS to bin numerical variables and give each group a meaningful name
Sometimes a little thing can make a big difference. I am enjoying a new enhancement of SAS/IML 15.1, which enables you to use a numeric vector as the column header or row header when you print a SAS/IML matrix. Prior to SAS/IML 15.1, you had to use the CHAR or
