SAS A00-231 Exam Topics:
Access and Create Data Structures (20-25%)
|Create temporary and permanent SAS data sets.
|- Use a DATA step to create a SAS data set from an existing SAS data set.
|Investigate SAS data libraries using base SAS utility procedures.
- Use a LIBNAME statement to assign a library reference name to a SAS library.
- Investigate a library programmatically using the CONTENTS procedure.
- Access SAS data sets with the SET statement.
- Use PROC IMPORT to access non-SAS data sources.
- Use the SAS/ACCESS XLSX engine to read a Microsoft Excel workbook.xlsx file.
|Combine SAS data sets.
- Concatenate data sets.
- Merge data sets one-to-one.
- Merge data sets one-to-many.
|Create and manipulate SAS date values.
- Explain how SAS stores date and time values.
- Use SAS informats to read common date and time expressions.
- Use SAS date and time formats to specify how the values are displayed.
Control which observations and variables in a SAS data set are processed and output.
- Use the WHERE statement in the DATA step to select observations to be processed.
- Subset variables to be output by using the DROP and KEEP statements.
- Use the DROP= and KEEP= data set options to specify columns to be processed and/or output.
Manage Data (35-40%)
|Sort observations in a SAS data set.
- Use the SORT Procedure to re-order observations in place or output to a new dataset with the OUT= option.
- Remove duplicate observations with the SORT Procedure.
|Conditionally execute SAS statements.
- Use IF-THEN/ELSE statements to process data conditionally.
- Use DO and END statements to execute multiple statements conditionally.
|Use assignment statements in the DATA step.
- Create new variables and assign a value.
- Assign a new value to an existing variable.
- Assign the value of an expression to a variable.
- Assign a constant date value to a variable.
|Modify variable attributes using options and statements in the DATA step.
- Change the names of variables by using the RENAME= data set option.
- Use LABEL and FORMAT statements to modify attributes in a DATA step.
- Define the length of a variable using the LENGTH statement.
|Accumulate sub-totals and totals using DATA step statements.
- Use the BY statement to aggregate by subgroups.
- Use first. and last. processing to identify where groups begin and end.
- Use the RETAIN and SUM statements.
|Use SAS functions to manipulate character data, numeric data, and SAS date values.
- Use SAS functions such as SCAN, SUBSTR, TRIM, UPCASE, and LOWCASE to perform tasks such as the tasks shown below.
- Use SAS numeric functions such as SUM, MEAN, RAND, SMALLEST, LARGEST, ROUND, and INT.
|Use SAS functions to convert character data to numeric and vice versa.
- Explain the automatic conversion that SAS uses to convert values between data types.
- Use the INPUT function to explicitly convert character data values to numeric values.
- Use the PUT function to explicitly convert numeric data values to character values.
|Process data using DO LOOPS.
- Explain how iterative DO loops function.
- Use DO loops to eliminate redundant code and to perform repetitive calculations.
- Use conditional DO loops.
- Use nested DO loops.
|Restructure SAS data sets with PROC TRANSPOSE.
- Select variables to transpose with the VAR statement.
- Rename transposed variables with the ID statement.
- Process data within groups using the BY statement.
- Use PROC TRANSPOSE options (OUT=, PREFIX= and NAME=).
|Use macro variables to simplify program maintenance.
- Create macro variables with the %LET statement
- Use macro variables within SAS programs.
Error Handling (15-20%)
|Identify and resolve programming logic errors.
- Use the PUTLOG Statement in the Data Step to help identify logic errors.
- Use PUTLOG to write the value of a variable, formatted values, or to write values of all variables.
- Use PUTLOG with Conditional logic.
- Use temporary variables N and ERROR to debug a DATA step.
|Recognize and correct syntax errors.
- Identify the characteristics of SAS statements.
- Define SAS syntax rules including the typical types of syntax errors such as misspelled keywords, unmatched quotation marks, missing semicolons, and invalid options.
- Use the log to help diagnose syntax errors in a given program.
