SAS Tutorials: Transposing Data using PROC TRANSPOSE
Webb14 nov. 2012 · • There are two types of data structure: wide and long. The wide format means one-record-per- person, and the long format means multiple-record-per-person. • Different analyses may need different data formats. • Stata has a built-in command called “reshape” to change the data structure, but SAS needs to use array to do so. WebbReshaping data from long (tall) to wide (fat) formats Merging datasets To reshape datasets, we will cover two methods PROC TRANSPOSE Using a DATA step with arrays In order to understand the second more general method, we will first need to learn about a few SAS programming keywords and structures, such as The OUTPUT and RETAIN … hayes racing syndicates

WebbFor a data set in wide format such as the one below, we can reshape it into long format using proc transpose. From the first output of proc print, we see that the data now is in long format except that we don’t have a numeric variable indicating year; instead; we have a character variable that has information on year in it.
