What is the definition of ID statement when using PROC transpose?
Specifies one or more variables in the input data set whose nonmissing formatted values name the transposed variables in the output data set.
How do you transpose a Procose?
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 .
How do you add a prefix in Proc transpose?
The PREFIX= option is used to place a prefix in the transposed variable names. For example, since PREFIX = score_ is used in the PROC TRANSPOSE statement, the names of the transposed variables will be SCORE_1 and SCORE_2. You can also use the SUFFIX= option to attach a suffix in the transposed variable name.
How do you change data from long to wide in SAS?
Simple proc transpose in SAS – long to wide
- Step 1: Sort by BY variable. Here BY variable is employee.
- Step 2: Mention PROC TRANSPOSE . BY Variable (employee variable) will become the Row of the transposed table. ID Variables becomes column of the transposed data. VAR becomes values inside.
How do you write a proc frequency?
Syntax. PROC FREQ DATA=sample ORDER=freq; TABLE State Rank; RUN; The ORDER=freq option in the first line of the syntax tells SAS to order the values in the table in descending order.
How do you use Proc contents?
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.
How do I label the transposed variables in Proc transpose?
PROC TRANSPOSE uses the values of the variable Student to label the transposed variables. The procedure provides the following as the label for the _NAME_ variable:NAME OF FORMER VARIABLE
How do I handle duplicate id values in Proc transpose?
Typically, each formatted ID value occurs only once in the input data set or, if you use a BY statement, only once within a BY group. Duplicate values cause PROC TRANSPOSE to issue a warning message and stop. However, if you use the LET option in the PROC TRANSPOSE statement, then the procedure issues a warning message about duplicate ID values.
What does Proc transpose truncate to?
The procedure truncates to 32 characters any ID value that is longer than 32 characters when the procedure uses that value to name a transposed variable. If the formatted value looks like a numeric constant, then PROC TRANSPOSE changes the characters +, -, and . to P, N, and D, respectively.
Does the procedure transpose observations that have a missing value?
The procedure does not transpose observations that have a missing value for any ID variable. names one or more variables whose formatted values are used to form the names of the transposed variables. Typically, each formatted ID value occurs only once in the input data set or, if you use a BY statement, only once within a BY group.
