The DO Loop
Statistical programming in SAS with an emphasis on SAS/IML programs
A SAS user asked an interesting question on the SAS/GRAPH and ODS Graphics Support Forum. The question is: Does PROC SGPLOT support a way to display the slope of the regression line that is computed by the REG statement? Recall that the REG statement in PROC SGPLOT fits and displays
The SAS/IML language has a curious syntax that enables you to specify a "repetition factor" when you initialize a vector of literal values. Essentially, the language enables you to specify the frequency of an element. For example, suppose you want to define the following vector: proc iml; x = {1
Suppose that you have a SAS/IML matrix and you want to set each element of a submatrix to zero (or any other value). There is a simple syntax that accomplishes this task. If you subscript a matrix and do not specify a row, it means "use all rows." So, for
