OUT=datasetname. this feature is used to create a brand new SAS dataset from a approach. (This choice should be illustrated in upcoming examples.) method STATEMENTs are usually required to point information regarding how an research is to be played. for instance, within the code PROC PRINT; VAR identity crew TIME1 TIME2; RUN; the VAR assertion exhibits that in simple terms the indexed variables are for use within the process. Statements can themselves have thoughts. for instance: PROC FREQ; TABLES GROUP*SOCIO/CHISQ; RUN;.
assertion permits you to specify which output could be integrated in an research. this is often various from the subsetting IF statements defined in bankruptcy three. In that bankruptcy, the subsetting IF assertion within the info step dictates which files are saved in an information set for next analyses on that individual info set. The the place assertion impacts in simple terms the information used for a selected process. for instance, within the identity instance, feel you must output info just for remedy A within the PROC PRINT.
