What is the purpose of the PROC TRANSPOSE procedure in SAS?

The PROC TRANSPOSE procedure in SAS is specifically designed to rotate the data structure by converting rows into columns. This is particularly useful when you need to restructure your dataset for analysis or reporting purposes. For instance, if you have a dataset where different measurements are represented as rows for each subject, you might want to transpose it so that each subject's measurements appear as columns instead.

This transformation allows for easier comparison and analysis, making it simpler to generate reports or charts that require data in a wide format rather than a long format. By using PROC TRANSPOSE, you effectively reshape your data, facilitating further statistical analysis or visualization.

Other options suggest functions that PROC TRANSPOSE does not perform. Analyzing data, sorting, and merging are handled by different procedures in SAS, such as PROC SORT for sorting and DATA step or PROC SQL for merging datasets.
