What does Proc transpose do in SAS?
Creates an output data set by restructuring the values in a SAS data set, transposing selected variables into observations. Tip: You can use data set options with the DATA= and OUT= options. For more information, see Statements with the Same Function in Multiple Procedures.
Which statement in proc transpose specifies the variables that will not be transposed in the resulting data set?
THE DEFAULT FORMAT FOR TRANPOSING BY-GROUPS You can specify more than one variable in the BY statement. To use the BY statement in PROC TRANSPOSE, the data set must be previously sorted by using the same BY-variable. The BY-variable is not transposed.
