What is the difference between proc means and proc summary?
Proc SUMMARY and Proc MEANS are essentially the same procedure.
Both procedures compute descriptive statistics.
The main difference concerns the default type of output they produce.
Proc MEANS by default produces printed output in the LISTING window or other open destination whereas Proc SUMMARY does not..
What does Proc mean?
ABSTRACT. PROC MEANS is a basic procedure within BASE SAS® used primarily for answering questions about quantities (How much?, What is the average?, What is the total?, etc.) It is the procedure that I use second only to PROC FREQ in both data management and basic data analysis.
What does %let mean in SAS?
%let creates a macro variable. The value of the macro variable is stored in the macro table. Before the value of the macro variable goes into the symbol table, macro triggers ( & and % are resolved or executed).
What is a SAS library?

How do you change a variable in SAS?
SAS uses the BESTw. format, where w is the width of the character variable and has a maximum value of 32. You cannot change the type of a variable. You will need to create a new variable from the old variable with the new data type and then drop and rename to keep the original names.
How do you create data in SAS?
Begin the DATA step and create a SAS data set called WEIGHT. Specify the external file that contains your data. Read a record and assign values to three variables. Calculate a value for variable WeightLoss.
How do you use proc frequency?
Syntax. PROC FREQ DATA=sample ORDER=freq; TABLE State Rank / MISSING; RUN; The ORDER=freq option in the first line of the syntax tells SAS to order the values in the table in descending order.
What does Proc mean in LoL?

What is Proc Freq?
Proc FREQ is a procedure that is used to give descriptive statistics about a particular data set. Proc FREQ is used to create frequency and cross-tabulation tables. It enables analysis at various levels. Associations between variables and responses can be tested and computed.
How do you transpose data in SAS?
The general format of PROC TRANSPOSE is: PROC TRANSPOSE DATA=Dataset-name OUT=New-dataset-name; BY variable(s); COPY variable(s); ID variable; VAR variable(s); RUN; In the SAS code above: The PROC TRANSPOSE statement tells SAS to execute the transpose procedure on an existing dataset called Dataset-name .

What does Proc print mean in SAS?
PROC PRINT sometimes conserves space by splitting labels across multiple lines. … For information about using the LABEL statement in a DATA step to create permanent labels, see LABEL Statement in SAS DATA Step Statements: Reference.
How do you write a PROC content in SAS?
The basic syntax of PROC CONTENTS is: PROC CONTENTS DATA=sample; RUN; As with all SAS procedures, the DATA command (which specifies the name of the dataset) is optional, but recommended. If you do not specify a dataset, SAS will use the most recently created dataset by default.
