How do you transpose variables 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 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.
How do I transpose columns to rows in SAS?
To transpose columns:

- Select Transpose in the transforms list.
- On the ID Columns tab, specify the columns that contain the row values that you want to transform into columns.
- (Optional) On the Transpose Columns tab, specify the columns that contain the data with which you want to populate the output table.
How do you use Retain in SAS?
The RETAIN statement simply copies retaining values by telling the SAS not to reset the variables to missing at the beginning of each iteration of the DATA step. If you would not use retain statement then SAS would return missing at the beginning of each iteration. The retain statement keeps the value once assigned.
What statement is used in Proc transpose to group the data?

How do you order columns in Proc transpose?
Proc transpose creates the columns as it sees new values of the ID variable.

Then the WHERE= dataset option deletes the extra group from the output.
How do you transpose in SAS EG?

How do I transpose columns in SAS?
The NAME= option allows you to change the name of the _NAME_ variable. It is the name of the variable that is transposed. 2. The PREFIX= option allows you to change the prefix “COL”….SAS : PROC TRANSPOSE with Examples.
Why is transpose data important?
Transpose creates a new data file in which the rows and columns in the original data file are transposed so that cases (rows) become variables and variables (columns) become cases. To retain any of these values, change the definition of missing values in the Data Editor. …
What is Proc Ttest in SAS?
The ttest procedure performs t-tests for one sample, two samples and paired observations. The single-sample t-test compares the mean of the sample to a given number (which you supply).
