How Do You Transpose Data In SAS?

What is transpose in SPSS?

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.

Transpose automatically creates new variable names and displays a list of the new variable names..

Does SAS Do Until statement?

The DO UNTIL statement evaluates the condition at the bottom of the loop; the DO WHILE statement evaluates the condition at the top of the loop. Note: The statements in a DO UNTIL loop always execute at least one time, whereas the statements in a DO WHILE loop do not iterate even once if the condition is false.

How do you restructure data in SPSS?

Do loops SAS macro?

In the DATA step, you can use the DO-END construct to loop through data. In the SAS Macro Language, you can use the %DO-%END construct to build SAS code. Index is a valid macro variable name. The names “I” for ‘index’ or “N” for ‘number’ are frequently used as the Index name.

How do you transpose character variables in SAS?

In order to transpose both numeric and character, you must list all variables to be transposed on the VAR statement. Mixed data values of character and numeric that will occupy the same column must be of the same data type in accordance with SAS data rules. All numeric values are converted to character.

What is proc transpose in SAS?

PROC TRANSPOSE is a powerful yet underutilized PROC in the Base SAS® toolset. … It contains three sample SAS® input files, a set of basic PROC TRANSPOSE variations, and their output results. There is a Summary Sheet at the end of the paper as well for later reference.

Do loop SAS data step?

Iterative DO loops are the simplest form of DO loops that can be executed within a SAS Data Step. The actions of an iterative DO loop are unconditional, meaning that if you define a loop to execute 50 times, it will execute 50 times without stopping (unless an error occurs during processing).

How do you remove duplicates in SAS PROC SQL?

Two approaches to removing duplicates will be illustrated, both using the DISTINCT keyword in a SELECT clause. Using PROC SQL and the DISTINCT keyword provides SAS users with an effective way to remove duplicate rows where all the columns contain identical values.

How do you format in SAS?

Rules for defining FORMAT NAME:For character values, first character must be a dollar sign ($), and a letter or underscore as the second character. … Name cannot end with a number.Cannot be the name of an existing SAS format.Should not end with a period in the VALUE statement.

What is Proc Tabulate in SAS?

Proc tabulate is predominately used to make nice looking tables. Unlike proc freq this procedure can handle multiple variables in the row and column expressions. It can also handle multiple levels in both rows and columns whereas proc freq will only create two variable contingency tables.

What does Proc format do in SAS?

PROC FORMAT is a procedure that creates map- pings of data values into data labels. The user de- fined FORMAT mapping is independent of a SAS DATASET and variables and must be explicitly as- signed in a subsequent DATASTEP and/or PROC. PROC FORMAT will not allow 1-to-many or many- to-many mappings.

How do I merge in SAS?

To perform a one-to-one merge, use the MERGE statement without a BY statement. SAS combines the first observation from all data sets in the MERGE statement into the first observation in the new data set, the second observation from all data sets into the second observation in the new data set, and so on.

How do I rename a column in Proc transpose?

Instead of using the RENAME= data set option to rename the _LABEL_ variable, you can also use the LABEL= option from the PROC TRANSPOSE statement to rename the _LABEL_ variable.

How do you transpose data in Excel?

Start by selecting and copying your entire data range. Click on a new location in your sheet, then go to Edit | Paste Special and select the Transpose check box, as shown in Figure B. Click OK, and Excel will transpose the column and row labels and data, as shown in Figure C.

How do I transpose a SAS dataset?

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 I transpose data in SPSS?

How to Transpose Data in SPSS From the Data menu, select Restructure… Then select “Restructure selected cases into variables”. For the “Identifier Variable(s)” box, transfer over the ID variable. … Select “Yes” to “Sort the current data”. Click Finish and the data should be restructured to a wide format.

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.

Where are SAS formats stored?

Permanent SAS data sets can be created by specifying a two-level dataset name. Formats created using PROC FORMAT are stored in format catalogues. By default, the format catalogue is stored in the work directory and deleted at the end of the SAS session (along with temporary data sets).

How do I use labels in SAS?

Labeling values is a two step process. First, you must create the label formats with proc format using a value statement. Next, you attach the label format to the variable with a format statement. This format statement can be used in either proc or data steps.

How does retain work 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.
